Add your APNG file
Drop one or more .apng files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .apng image to .png re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .apng image to .png re-encodes the pixels for a different balance of size, quality, and support. An .apng file is an animated extension of PNG: full 24-bit color with 8-bit alpha per frame, in a stream that plain PNG decoders read as a normal still image. It delivers the smooth, semi-transparent animation that GIF's 256-color palette never could, and it is the format behind many messaging-app sticker packs.
A .png file is a losslessly compressed raster image with full 8-bit alpha transparency, making it the standard choice for graphics that must stay pixel-perfect. Screenshots, logos, UI assets, and diagrams are the classic .png territory, since sharp edges and flat color survive without compression artifacts. For this route the practical draw is perfectly lossless, so files can be opened and re-saved indefinitely and true 8-bit (or 16-bit) alpha channel — balanced against photographic content produces files several times larger than JPEG or WebP, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .apng, files grow quickly for long or high-motion animations, where animated WebP/AVIF or video compress far better. Switching to .png buys you perfectly lossless, so files can be opened and re-saved indefinitely, which is why it is the better fit for screenshots and screen recordings exported as stills. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Animated PNG (.apng) | PNG image (.png) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | adds three chunk types to PNG: acTL (animation control), fcTL (frame control), and fdAT (frame data) | uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth) |
| Strongest at | animated stickers (Apple's iMessage and LINE both build on APNG) | screenshots and screen recordings exported as stills |
| Weak spot | files grow quickly for long or high-motion animations, where animated WebP/AVIF or video compress far better | photographic content produces files several times larger than JPEG or WebP |

Select .png in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if PNG is selectable, the route is real and validated.
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid PNG file. Outputs keep the original filename with the .png extension.
Since apng is lossless-oriented and png is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .png itself requires.
Yes — the .apng file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Every modern browser has rendered PNG with full alpha since Internet Explorer 7 fixed its transparency bug in 2006, and native OS support is universal on Windows, macOS, Linux, iOS, and Android. It is also the required format in many contexts, such as iOS app icons and favicon fallbacks.
It depends on the content: uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth). Convert one representative file first and compare before batch-processing a large set.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .apng → .png → .apng is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
