Drop your GIF files into the emerald zone below to create a PDF. Most converters push a GIF through a JPEG filter, which is the worst available choice for 256-color artwork: it smears hard edges, speckles flat color and puts halos around text. This engine rewrites your GIF as a lossless PNG instead, so every pixel in the document matches the pixel in your file. Animated files are detected and flagged before you convert. The work runs on your own CPU and nothing is uploaded.
Your files are read by JavaScript running on your own machine. There is no upload, no queue, and no copy on our server to delete later.
Drag a card to reorder it, or use the arrows under each card. The order here is the order in the output. Each card is a preview of the finished page, so what you see is what the PDF will contain.

This is your processor doing the work, so the time it takes depends on your machine and not on how many other people are on the site.
The converter above is already running, with no setup required. The engineering notes below explain the decision most PDF tools get wrong - why sending a 256-color image through a photographic compression filter wrecks it, what actually happens to animated frames inside a static document format, and how local processing keeps your files off the network entirely.
Two minutes. Nothing to install, and no account for a basic run. This GIF to PDF converter runs as JavaScript inside the page you are reading right now, using your own hardware and nothing else.
Click the drop zone above or drag your GIFs onto the page. The script walks the GIF block chain as each file lands, reading the real pixel dimensions and counting the image descriptors to get a frame count. All of that happens before conversion starts. Nothing is a surprise afterwards.
A card reading "animated GIF, first frame only" means the script found more than one frame in that file. PDF pages do not animate. Only the first frame is exported, and knowing that before you convert is the difference between a deliberate choice and a broken document.
Card order is page order, so drag the cards until the sequence is right. Then choose A4 or US Letter to scale your graphics onto standard business sheets, or Fit to image to build each page at the native pixel dimensions of the graphic.
Press Convert to PDF. Open the result and zoom to 100 percent on a line of text or a sharp boundary. It will be exactly as crisp as your source. No blur, no speckling, no halos along the edges. If you have ever seen artifacts around text in a converted PDF, another tool put them there.
A PDF cannot carry a GIF. The specification accepts a fixed set of image filters, among them DCTDecode for JPEG, FlateDecode for deflate-compressed pixels and JBIG2Decode for bilevel scans. GIF uses LZW compression over palette indices, which is on none of those lists, so the image has to be decoded and repacked into something the container will accept.
That repack is where converters separate. Most reach for JPEG because the PDF libraries make it a one-line call. For a GIF, that is the worst option available.
JPEG is a photographic codec. It compresses by discarding high-frequency detail the eye tends not to miss in a continuous-tone photograph, on the assumption that the picture is full of smooth gradients. A GIF is the opposite kind of image: at most 256 colors, large areas of flat color, and abrupt hard boundaries everywhere.
Force a GIF through a JPEG encoder and every one of those assumptions breaks. Ringing halos appear along the hard edges, mosquito noise settles around the typography, and blocks of flat color turn mottled. None of that damage was necessary, because the GIF you started with was already lossless.
We took the other route. The engine decodes your GIF and rewrites it as a lossless PNG, embedded with FlateDecode. Every pixel value in the finished PDF matches the value in your source file. Text stays sharp.
| Conversion Route | Data Loss | Visual Result | File Weight |
|---|---|---|---|
| Repacked as PNG (CartHacker) | None. Pixel identical. | Matches the source exactly. | Usually larger than the GIF; the FAQ says why. |
| Forced through JPEG (typical) | Permanent. | Ringing halos, speckling, damaged text. | Also larger. Flat color compresses badly in JPEG. |
The file weight column is worth reading twice. Neither route reliably shrinks a GIF, and JPEG certainly does not: flat color and hard edges are exactly what a discrete cosine transform handles worst, so a diagram pushed through JPEG often comes out both heavier and visibly worse. Since neither option saves space, there is no reason to accept the one that also destroys quality.
The card tells you what happened. When it reads GIF repacked losslessly as PNG, that is a statement about your specific file rather than a slogan on a landing page. Zoom the finished document to 100 percent and check a hard edge against the original.
A PDF page is a fixed arrangement of marks on digital paper, and there is no timeline anywhere in the format for an animation to run along. No online pdf editor can add one. Process an animated GIF here and what you get is the first frame. That is the whole story.
What differs here is that you are told first. The moment a file lands, the script walks its block chain and counts the image descriptors. A 40 frame animation produces a card reading animated GIF, first frame only, and you decide whether to spend an operation on it.
That gives you a flipbook, one frame per page. It is a genuinely useful format for documenting an interface interaction, getting a client to sign off on an ad creative, or walking an engineering review through a sequence frame by frame.
On volume: a handful of frames is nothing for the free engine. Anonymous visitors get one operation every 12 hours; a free CartHacker account raises that to two. Both cap a batch at 20 files or 100 MB. CartHacker Premium removes the operation counter and lifts that ceiling to 100 files and 500 MB, which is what a few hundred product schematics actually needs.
A GIF holds a palette of at most 256 colors, and every pixel on the canvas is an index pointing into that palette. For flat artwork the indirection is efficient. For photographs it is destructive: squeeze a full-color photo into 256 entries and you get banding across every gradient, usually with a dithering pattern scattered over it to disguise the shortage.
The converter cannot invent data that was thrown away when the file was first exported. If your source GIF is heavily dithered, the PDF reproduces that dithering exactly, because reproducing the source exactly is the entire design goal. No converter restores a color range the format already discarded.
GIF transparency is a flag on one palette entry, not an alpha channel. Every pixel is either fully opaque or fully invisible, with no middle ground at all. That is the whole mechanism.
This is why a curved logo or a diagonal edge over a transparent background looks stepped and pixelated in a GIF. There is no way to store a half-transparent pixel to smooth the transition. PNG solved it in 1996 with a true 8-bit alpha channel, giving 256 levels of opacity and therefore proper anti-aliasing.
When the GIF is rewritten for the PDF, that binary transparency carries across accurately as a soft mask. The edges stay exactly as ragged as they were in the source, because the intermediate opacity values were never in the file to begin with. If you need smooth anti-aliased edges, you need the original artwork as a PNG rather than a GIF.
The usual model for a free pdf converter is to upload your files to a cloud server, hold them in a queue, and point you at a privacy policy promising deletion. That promise is worth whatever the next server backup, the next staff change and the next acquisition leave of it.
This tool was built without the cloud step. The JavaScript engine on this page uses the HTML5 File API to read your graphics straight into local memory. The conversion runs on your CPU and the document is assembled in your browser, so no server ever ingests your data.
Do not take that on trust. Load this URL, switch off your Wi-Fi, and process a file. It works, because there is no remote service for it to call.
The offline test. Disconnect the network cable or turn off Wi-Fi right now. Drop a file in and press convert. A cloud tool fails immediately. This one hands you a finished document.
The only thing that leaves your machine is an anonymous operation counter enforcing the free tier limits. It logs that a batch completed and when. It never touches your file contents, your metadata or your file names.
No. A PDF cannot hold GIF data directly, so the script decodes the graphic and rewrites it as a lossless PNG rather than a lossy JPEG. Every pixel in the output matches the pixel in your source file. Hard edges stay crisp and flat color stays uniform.
JPEG is designed for photographs. A GIF is the opposite: a 256-color palette, large flat areas and harsh boundaries. Pushing that through JPEG produces ringing artifacts and mosquito noise around the typography. PNG keeps the image mathematically identical and, on flat artwork, usually produces a smaller file than JPEG would anyway.
Yes. Drop a batch of images in and leave the Merge all images into one PDF option enabled. The engine sequences the pages from the card order on screen and compiles them into one multi-page document.
You get a static render of the first frame, because the PDF format has no animation timeline to put the rest on. The script counts the frames as the file lands and warns you on the card before you convert, so the limitation never arrives as a surprise.
Yes, it carries across into the PDF as a soft mask. Remember that GIF transparency is binary: a pixel is either fully opaque or fully invisible, with nothing in between. If the edges look jagged in the output, that stepping is already in your source file and no converter can smooth it after the fact.
That speckling is dithering. Because GIF caps out at 256 colors, whoever exported the graphic originally had to force a richer image into a very small palette, and the dithering pattern is baked permanently into the pixels. Our converter reproduces the source exactly, including its flaws.
Yes. The conversion runs as JavaScript inside your browser tab, on your own CPU. Your files are never uploaded, queued or processed by an external server, because the code has no endpoint to send them to.
GIF and PNG are both lossless but they compress very differently. GIF stores palette indices with LZW, which is efficient on small artwork with few colors, while the browser writes the replacement PNG with full-color samples rather than your original palette. Add the PDF container overhead and a small indexed GIF usually comes out larger. The pixels are identical either way.
Not from the animated file directly, which yields only the first frame. Split the frames with external software first, then drop the resulting sequence into the drop zone to build a page-by-page flipbook of the interaction.
A4 or US Letter if the document is going to be printed or filed in a corporate system. Use Fit to image to lock the page to the exact pixel dimensions of the graphic instead. One warning: scaling a low-resolution GIF up onto a full A4 sheet makes the missing pixel density painfully obvious, so check the result before you send it anywhere.
No. There is no forced branding, trial stamp or logo anywhere in the output. The document contains your source graphics and nothing else, which makes it usable commercially the moment it is generated.
Yes. Interlacing only affects how an image renders progressively over a slow connection. The browser decoder reads the whole data block and hands the fully assembled graphic to the PDF compiler, so the interlacing has no effect on the result.
Yes. The interface provides explicit sequence buttons on every card rather than relying on mobile drag-and-drop, which is unreliable. GIF files are small and indexed, so they decode comfortably on a modern phone without the memory pressure a batch of raw photographs would create.
Yes, and they are specific. Anonymous visitors get one operation every 12 hours and free accounts get two, with both capped at 20 files or 100 MB per batch. CartHacker Premium removes the operation counter and raises that ceiling to 100 files and 500 MB.
All of these run the same way: your file is read by JavaScript on your own machine, the work happens on your processor, and the result is handed back to you as a download that never existed anywhere else.
