Convert AVIF to PNG free, without uploading
AVIF to PNG grew our 1281×1600 px test portrait from 58.9 KB to 2.61 MB (+4,441%). PNG adds no compression loss, but colour deeper than 8 bits per channel is reduced to 8 bits. Drop the AVIF (.avif) on the tool below and download the PNG; nothing is uploaded.
AVIF to PNG
PNG · no file-size limit · original pixel size
No file-size limit is set: PixelFit saves at high quality and changes only the format and any pixel size you set.
Fit, background and padding white background
Saving presets is part of Pro.
The result appears here: the exact byte count, pixel size and quality, the size before and after, a preview and a download button.
The batch kit (one ZIP for up to 500 photos, several photos merged into one PDF) is part of Pro.
What changes from AVIF to PNG
3 of these 5 points lose or alter something on the way from AVIF to PNG; the rest carry over.
- Kept: Transparency survives: PNG keeps the alpha channel of the AVIF.
- Lost or changed: AVIF can be animated; PixelFit writes a still PNG of the first frame only.
- Kept: PNG adds no compression loss of its own, but it cannot bring back detail the AVIF compression already removed. The bit-depth changes listed here still apply.
- Lost or changed: AVIF can hold more than 8 bits per channel (8, 10 or 12 bits per channel); a browser canvas works at 8 bits, so 10-, 12- or 16-bit files are reduced to 8 bits per channel.
- Lost or changed: Metadata is not carried over: the AVIF's EXIF and XMP items are dropped by the canvas, and EXIF orientation is applied to the pixels first so the photo stays upright.
Measured file size: AVIF vs PNG
sharp 0.35.5 / libvips 8.18.7, 31 October 2026, long edge 1600 px; PNG saved as lossless, zlib level 6, RGBA, AVIF as quality 50, effort 4 (PixelFit reads AVIF but does not write it). The PNG column is the AVIF file decoded and saved again, as PixelFit does.

What the numbers mean for AVIF to PNG
Our portrait photo at 1281×1600 px: AVIF 58.9 KB → PNG 2.61 MB (+4,441%, 45.4 times larger).
Our landscape photo at 1600×1200 px: AVIF 239 KB → PNG 3.86 MB (+1,557%, 16.6 times larger).
Our scanned typed letter at 1273×1600 px: AVIF 99.1 KB → PNG 1.31 MB (+1,250%, 13.5 times larger).
Our flat chart with a transparent background at 1600×1000 px: AVIF 5.7 KB → PNG 76 KB (+1,244%, 13.4 times larger).
Per pixel, the portrait took 0.24 bits as AVIF and 10.69 bits as PNG, a difference of 2.56 MB on 2,049,600 pixels.
Per pixel, the chart took 0.03 bits as AVIF and 0.39 bits as PNG, a difference of 70.4 KB on 1,600,000 pixels.
PNG came out larger than AVIF on all 4 samples, by +1,244% to +4,441%.
Reducing the portrait PNG to 256 colours brought it down to 782 KB (made from the original photo), still 3.1 times a quality 85 JPG, and a 256-colour palette can band smooth skin and sky tones.
How to convert AVIF to PNG
-
Add the AVIF file
Drop the .avif file on the tool at the top of this page, tap to choose it, or paste it.
-
Keep PNG selected
PNG is pre-selected and saved in full colour. Type a maximum size in KB only if the destination sets one; PixelFit then tries fewer colours (a palette PNG) and, if that is not enough, fewer pixels. Our AVIF test portrait came out at 2.61 MB as PNG with no limit set.
-
Download the PNG
Save the file ending in .png; its size in KB shows before you save.

When not to change AVIF to PNG
- Do not change AVIF to PNG to make a photo smaller: our portrait grew +4,441%, from 58.9 KB to 2.61 MB, with no gain in quality.
- Changing AVIF to PNG does not restore detail; do it only when the destination demands PNG or you will edit the image further.
- If the destination already accepts AVIF, upload the original: every change of format re-encodes the pixels.
Browser support for AVIF and PNG (October 2026)
Reading AVIF (.avif): Chrome 85+, Edge 121+, Firefox 93+, Safari 16.4+. caniuse puts AVIF support at about 96.33% of browsers in use (data updated 29 October 2026).
Writing PNG from that AVIF: Chrome 50+, Edge 79+, Firefox 18+, Safari 11+ (MDN compatibility data for canvas.toBlob, checked 31 October 2026).
AVIF reached Safari later than Chrome and Firefox, so iPhones and Macs older than Safari 16.4 may not open it; current versions do.
Upload forms that ask for PNG
10 of the 61 application portals we checked accept PNG photos, 1 of them with a limit of 50 KB or less. A few of them, for this AVIF file (verify with the official notice before you upload):
- Japan eVISA: PNG photo, up to 2 MB (also takes JPG, GIF, BMP, HEIC).
- Oman eVisa: PNG photo, up to 512 KB (also takes JPG, PDF).
- Singapore ABTC: PNG photo, up to 8 MB, 400 × 514 px (also takes JPG, HEIC).
- Indonesia e-VOA: PNG photo, up to 200 KB (also takes JPG).
Where AVIF files come from
AVIF files mostly come from websites that serve the newest image format to modern browsers. Saving one gives you an .avif that many desktop apps and forms cannot open, so it is changed to PNG for reuse.

Frequently asked questions
Can I convert AVIF to PNG for free?
Yes. The AVIF to PNG change runs free on your device, with no sign-up and no upload, one file or up to 25 at a time; Pro raises the batch to 500 with one ZIP download.
How do I convert AVIF to PNG?
Drop the AVIF on the tool above, keep PNG selected, and download the .png file. Add a KB limit if the destination has one.
Does converting AVIF to PNG reduce quality?
PNG adds no compression loss of its own, but it cannot bring back detail the AVIF compression already removed. The bit-depth changes listed here still apply. In our test a 1281×1600 px portrait went from 58.9 KB as AVIF to 2.61 MB as PNG (+4,441%).
Why convert AVIF to PNG?
PNG suits screenshots, logos, signatures on white and images with transparency; AVIF is a poor fit for older apps, photo editors and most upload forms, which do not open it.
