How to convert TIFF to GIF without uploading it
TIFF is the archival format: scanners, print shops and pre-press workflows save in TIFF because it keeps every pixel at full quality. But the places you actually share images — Discord, Slack, email, forums, CMS upload forms — often cannot play a TIFF inline, or reject it outright. Every "free" online TIFF converter you've used uploads your scans to a company server, converts them there, and — in several documented cases — keeps a copy or a live download link for days. For personal scans and anything you wouldn't post publicly, that's an unnecessary risk. The safer approach is to convert the file where it already is: on your own device.
This tool does exactly that. When you drop a TIFF here, your browser:
- Decodes the TIFF in your browser with the bundled UTIF.js decoder — every page of a multi-page TIFF, in order, including LZW, PackBits, Deflate and uncompressed scans, plus greyscale, palette-colour and CMYK files.
- Flattens any transparency onto your chosen background colour and quantises the pixels to at most 256 colours — GIF has no soft transparency and no 16-bit mode, so 16-bit scans are tone-mapped to 8-bit and metadata is dropped. TIFF orientation tags are NOT applied, so a scan stored sideways stays sideways.
- Re-encodes the pixels as a GIF with a JavaScript GIF encoder — one still GIF per file from the first page, or one frame per page in combine mode. Your original file is never modified.
Still GIF or combined GIF — which should you pick?
Pick still GIF when you need one shareable image per file — a reaction image, a sticker, or a scan that has to open in an app that cannot read TIFF. Still mode converts the first page of each TIFF only, and the card says so plainly ("page 1 of N"). Pick combine when the pages belong together: every page of every TIFF becomes one frame of a single looping GIF, so a 3-page scanned document plays as a 3-frame animation. A single page always makes a still GIF — one page holds one still image, so it cannot animate on its own.
Why does the GIF look worse than the TIFF?
GIF was designed in 1987 for simple graphics, and it stores at most 256 colours per frame. A photo or a smooth scan contains thousands of shades, so the converter has to pick the 256 that matter most and dither the rest — speckling pixels to fake the missing shades. Smooth skies, skin, and gradients suffer most; flat graphics, logos, line art and text survive well. That is a limit of the format, not a defect in the conversion. If the scan has to look its best, keep it as a TIFF: TIFF keeps scans sharp and full-colour. If it has to be lossless, use our TIFF to JPG converter instead.
When is GIF the right choice for a TIFF?
TIFF is the best format for a scan that just needs to be stored or printed — sharp, full colour, and supported by every serious image tool. GIF earns its place when the picture has to be seen and shared: some chat apps, forums, email clients and upload forms won't play a TIFF inline, reject it as an attachment type, or strip it to a download link, while a GIF opens everywhere and even plays inline. GIF is also the only widely supported format that animates, which is what combine mode is for. If the destination has a size limit, pick a destination preset and the converter will aim for it.
Honest limitations
Only 256 colours
Photos lose detail and smooth gradients band or dither. Dithering softens the banding but adds a speckled texture. For faithful scans, keep the TIFF or convert to JPG instead.
GIFs are larger than TIFFs for photos
Expect a photo GIF to be bigger than the TIFF it came from, and an animated GIF to grow with every frame. There is no quality slider that makes a GIF small — only fewer colours, a smaller width, or fewer frames. Flat graphics usually shrink.
Still mode converts the first page only
A multi-page TIFF in still mode becomes one GIF from page 1. The card says "page 1 of N" so nothing is hidden — use combine mode to animate all pages as one GIF.
Orientation tags are NOT applied
TIFF orientation tags are read and reported, but the GIF keeps the stored orientation. A scan stored sideways comes out sideways — rotate it in your image editor first.
Metadata is stripped, 16-bit is tone-mapped
Camera and scanner metadata (EXIF, including location) is dropped on re-encode. 16-bit TIFFs are tone-mapped down to 8-bit, so some shadow and highlight detail is lost. JPEG-compressed TIFFs are untested with this decoder.
