How to Convert to PDF

  1. 1

    Drop your GIF files

    Add up to two hundred images at once. Each file is inspected before anything happens, so you learn how many frames an animation has before you press a button.

  2. 2

    Set page size and background

    Keep the page the size of the picture, or fit everything to A4 or Letter with margins. Pick white, black or a transparent background for the see-through parts.

  3. 3

    Download the PDF

    Press the button and save one document, or turn merging off and get a ZIP holding one PDF per image.

One frame, no colour loss

A GIF is a palette image of at most 256 colours, often with hard edges: pixel art, screen recordings, chart animations. Running that through JPEG would put visible ringing around every outline, so pages here are always encoded as PNG, which stores a palette image without losing a pixel. Animation is the other half of the story. A PDF page cannot move, so only the first frame goes in, and rather than discovering that afterwards you are told how many frames the file holds while it still sits in the list.

Transparency and very small pictures

GIF transparency is a single palette index rather than a real alpha channel, and readers disagree about how to draw it: some show white, some black. That is why the background is a deliberate choice here. White is the default and looks the same everywhere, black suits light artwork, and transparent keeps the see-through areas with a warning that some viewers render them dark. Size is the other quirk: a page the exact size of a 32-pixel icon would be half an inch across, so a fitted page is raised to two inches on its shorter side and the picture scales with it.

Nothing is uploaded anywhere

The files are parsed, decoded and assembled into a PDF inside your browser tab, and the result is handed straight to your downloads folder. No server receives the images, nothing is queued for processing elsewhere, and there is no stored copy to worry about later or to ask anyone to delete. Everything disappears the moment you close the tab.

Frequently asked questions

Why doesn't the animation survive?

Because a PDF page is a still image; the format has no way to play a sequence of frames. Only the first frame is placed on the page, and the file is scanned beforehand so you know how many frames are being left out before you convert.

How do I get all the frames instead?

Extract them as separate images first, then bring those images back here. Each frame becomes its own page, which gives you a flip-book of the animation inside one document. The frame extractor is linked from the message about skipped frames.

What happens to transparent areas?

By default they are filled with white before the image goes into the page, which looks identical in every reader. Choose black if that suits the artwork better, or choose transparent to keep them, accepting that some viewers will show those areas as black.

Why PNG inside the PDF and not JPEG?

Because GIF is a palette format with at most 256 colours and usually hard edges. JPEG would add visible ringing around every outline and gain little, while PNG stores palette images without any loss at all. There is nothing to choose, so nothing is asked.

Why is my page bigger than the tiny GIF?

Because a page the exact size of a 32-pixel icon would be about half an inch across and unusable. When the page is fitted to the image, the shorter side is raised to two inches and the picture scales with it, keeping the original proportions.

How do I change the page order?

Pages follow the order in which you added the files, so drop them in the order you want them read. To rearrange the result, open it in the page organiser and drag pages into place, or start again with the files in a different order.

Can I get one PDF per image?

Yes. Turn merging off and each GIF becomes its own document, delivered together in a single ZIP, with each PDF named after the image it came from. Leave merging on and every picture becomes one page of one document.

Is there a limit on how many files?

Up to two hundred images at a time, and 500 MB in total. If you have more, convert them in batches and stitch the batches together with the merge tool afterwards, which is faster than asking one browser tab to hold everything at once.
