Simple 3-step flow
Drop up to 30 AVIF files, tune once, and download PNG files plus one ZIP — decoded and re-encoded in this tab.
01
Drop up to 30 AVIF files from this device. Each shows as a preview card with a live size estimate. Drag to reorder.
Batch of 30 · drag to reorder
02
Hit Convert. Your browser decodes the AVIF and re-encodes it as lossless PNG on a canvas locally.
No slider — lossless
03
Save each PNG individually or grab one ZIP for the batch. The sources on disk stay put.

What the workspace does
These match the converter — the pair rule, the quality rule, and local-only processing.
Alpha survives the trip — transparency is preserved in PNG output.
AVIF → PNG
PNG keeps every pixel exactly, so there is no quality slider — size is whatever lossless takes.
No slider needed
Privacy architecture
Cloud converters upload the image to flip its format remotely. This one decodes and re-encodes on a canvas here — the file never leaves the device.
Legacy cloud tools
Uploads the image to a remote queue.

Source stays on disk. Output is a fresh encode.
Honest output
Format conversion changes the container and compression — it never invents pixels, transparency, or detail.
Answers
Quality, transparency, and whether AVIF files are uploaded.
No. AVIF itself is typically lossy. PNG is lossless relative to the decoded pixels only.
When the browser decodes an alpha AVIF onto the canvas, PNG can keep it. Success depends on the decoder, not on a flatten colour we apply (we do not flatten AVIF on this route).
Almost certainly a browser AVIF profile gap. The error message points at browser support on purpose.
Only for compatibility. AVIF is newer and usually more compact; PNG is the format older editors still open. Keep the AVIF if the destination already accepts it.
Yes — up to 30 files per batch, each with its own estimate and download plus one ZIP. Files your browser cannot decode are rejected up front.
Constraints
Up to 30 images per batch — each with its own download, plus ZIP.
Browser must decode AVIF.
PNG — no quality slider.
