Empty side keeps the ratio. Never enlarges.
AVIF · 171 KB
PNG · 185 KBThe 2026 editor-compatibility reality sends everyone here. Photoshop still needs a plugin, Figma and Canva import AVIF inconsistently, Office and PowerPoint mostly refuse it, and GIMP is the lone editor with clean native support. PNG is the one format every editing tool opens with full fidelity and transparency. So for an onward-editing workflow, converting AVIF → PNG once beats fighting plugins forever.
PNG stores every pixel losslessly; AVIF stored a perceptual approximation. Undoing that compression costs bytes. How many depends on content:
| Output | Size | vs AVIF | Why |
|---|---|---|---|
| PNG (palette-optimised) | 189.5 KB | +8% | Faithful; bit-exact at q100 |
| JPG (quality 85) | 104 KB | -41% | Lossy, no alpha |
| WebP (Auto) | 108.2 KB | -38% | Lossy, keeps alpha |
Source: photo.avif, 175.3 KB photograph. Our PNG output is palette-optimised; a raw truecolour PNG would be several times larger still. Flat graphics grow far less than photos.
How these numbers are measured: every byte count on this page is the size of the actual encoded file our engine produced from the named source image. Those are the same bytes you would download, not an estimate or a best case. Rerun any of them yourself: drop your own file into the tool above and the meter reports your real result.
PNG and AVIF speak the same alpha language, so transparency converts intact, including the hard cases: semi-transparent drop shadows, feathered edges, anti-aliased text. The compare view renders edges against a checkerboard precisely so you can verify no fringing or banding appeared. If your file is a transparent logo, this is the conversion that keeps it a logo.
An honest definition, because converters love this word. At quality 100 the conversion is lossless from the decoded AVIF: truecolour PNG records exactly the pixels the AVIF produced, adds zero new loss, and every subsequent edit-and-save costs nothing. (At Auto, we palette-optimise the output for size instead.) What it cannot do is resurrect detail the original AVIF encoding already discarded; no converter can. Your PNG is a perfect copy of what the AVIF looked like, not of what the photo looked like before it became an AVIF.
Our output already applies palette quantization where it wins, the same technique behind every "smart PNG" tool. That is why the numbers above beat naive converters. Beyond that, be honest about the destination. If the image is a photograph headed for a document or the web, a quality-85 JPG or a WebP carries it at a fraction of the bytes, and Compress PNG can squeeze the file further after any edits.
Short answers specific to this page. The tool above settles most of them in a second.
Every route in and out runs on the same engine and the same rules. Each card is its own page.
Freeze the current pixels. Lossless from here, and the right move before editing or archiving.
For photographic PNGs that never needed transparency. We flatten any alpha onto a solid background.
Keeps the alpha channel and still cuts real weight. The least disruptive way off PNG.
Transparency survives and size collapses. Check thin type and 1px strokes in the preview first.
Keeps transparency for editors and pipelines that won't read WebP. Bigger file, no further loss.
When something rejects the upload, this is the format it wants. Photos only, no transparency.
Drop it in above. The meter reports the exact saving before you download anything.
