Turn TIF Images into an Animated APNG: What This Covers

This tool is an APNG maker: it stacks several .tif/.tiff images (or the pages of one multi-page TIFF) into a single animated PNG, where each image becomes one frame. You get a web-viewable, lossless-capable animation out of source images that no browser displays natively — with control over frame rate, quality, resolution, and palette.

How to Convert TIF to APNG

1. Upload Your TIF Files: Drag and drop or click "+ Add Files" to select several .tif/.tiff images in the order you want them to play, or upload one multi-page TIFF whose pages will each become a frame.
2. Set Framerate and Image Quality: Pick a Framerate — 10 FPS (recommended) is a safe slideshow speed; 24-30 FPS reads as motion. Leave Image Quality (%) at 80 for compressed output, or raise it toward 100 to keep more detail per frame.
3. Resize and Reduce Colors (Optional): Under Image resolution choose a preset, a custom Width x Height, or a percentage; under Colors keep ORIGINAL (full 24-bit) or pick By Color Reduction + Dither to cap the palette and shrink the file.
4. Convert and Download: Click "Convert". Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours — no sign-up, no watermark, batch supported.

Walk-through: Getting the Frame Order and Timing Right

The single most common surprise is frame order. When you upload a batch of separate TIFFs, they are sequenced alphanumerically by filename — not by the order you dragged them in. Name them frame_001.tif, frame_002.tif, … frame_010.tif (zero-padded) so frame_2 doesn't sort after frame_19. For a multi-page TIFF, frames follow the page (IFD) order already inside the file, which is normally the original scan or export order.

Framerate controls timing for the whole animation, not per-frame delays:

• Document or scan flipbook: 5-10 FPS gives each page enough dwell time to read.
• Time-lapse or stop-motion preview: 12-15 FPS looks like smooth slow motion without bloating the file.
• Motion sequence: 24-30 FPS reads as video; expect the file size to climb roughly in proportion to the frame count.
• One image only: the output is a valid single-frame APNG — a normal static PNG with no animation to play.

Unlike GIF, APNG carries full 24-bit RGB color and an 8-bit alpha channel, so gradients and soft transparent edges survive the conversion. In our testing, a 12-frame batch of 1080p photographic TIFFs at 10 FPS and 80% quality produced an APNG in the low single-digit megabytes — larger than the equivalent GIF in flat-color cases, but far cleaner on gradients and partial transparency.

Common Errors and How to Fix Them

• "My APNG isn't animating, it's just one image" — Either you uploaded a single TIFF, or the viewer doesn't support APNG and is showing the first-frame fallback. Confirm you added two or more frames, and open the file in Chrome, Firefox, Edge, or Safari rather than an OS thumbnail preview.
• "The frames are in the wrong order" — Batch frames sort by filename, not upload order. Rename with zero-padded numbers (001, 002, …) and re-upload.
• "The animation plays too fast or too slow" — Adjust the Framerate; 10 FPS is a calm slideshow, 24-30 FPS is motion speed.
• "The file is much bigger than I expected" — APNG is lossless by nature, so photographic frames stay heavy. Lower Image Quality (%), downscale under Image resolution, or reduce Colors with dithering.
• "Transparency looks wrong against a colored background" — APNG keeps the source alpha; if your TIFF had no alpha channel, transparent areas fill with the background the image was flattened onto.

When This Doesn't Work

APNG is the right target when you want a lossless, transparency-capable animation that plays in modern browsers (about 94.7% of users globally, per caniuse; everyone else sees the first frame). It is the wrong target when you need maximum reach on legacy software or chat platforms that still favor GIF, or when the animation is long and photographic — at that point APNG balloons and a video codec wins. For broadest compatibility use TIFF to GIF; for the smallest file on long sequences, render to MP4 with TIFF to MP4. To go the other way and pull frames back out, see APNG to TIFF.

Frequently Asked Questions

How do I combine several TIF files into one animated APNG?

Upload them as a single batch. Each .tif/.tiff you add becomes one frame, sequenced alphanumerically by filename, and the chosen Framerate sets how long each frame is shown. Zero-pad the names (frame_001.tif) so the order is exactly what you intend.

Does a multi-page TIFF become an animation automatically?

Yes. Every page (Image File Directory) inside the TIFF is read as a separate frame in page order, so a multi-page scan or an ImageJ/Fiji Z-stack exported as one TIFF turns into an APNG flipbook without splitting it first.

Will I lose quality or transparency converting TIF to APNG?

APNG stores 24-bit RGB color plus an 8-bit alpha channel and is internally lossless, so it preserves color depth and partial transparency far better than GIF. If you keep Colors on ORIGINAL and quality high, the per-frame fidelity matches your TIFF closely; reducing colors or lowering quality trades fidelity for a smaller file.

Which browsers play APNG, and what happens in the ones that don't?

Chrome (59+), Firefox (3+), Safari (8+), Edge (79+), and Opera (46+) all play APNG — roughly 94.7% of global users per caniuse. Any browser or app without APNG support shows only the first frame, so the file degrades gracefully to a static image instead of breaking.

Is APNG smaller than a GIF of the same animation?

Not usually for photographic or gradient content. APNG is lossless and 24-bit, so it tends to be larger than a 256-color GIF of the same clip, but it looks dramatically cleaner with no palette banding and supports soft transparency. For flat-color UI loops APNG can actually be competitive; for long photo sequences a video format is far smaller.

Are my uploaded TIF files kept or shared?

No. Files are uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and nothing is shared or made public.
