Why doesn't AVIF work in my browser?

Canvas AVIF encoding requires Chrome 85+, Edge 85+ or Chromium-based browsers. Safari and Firefox can display AVIF but can't yet encode it from Canvas. We detect this and disable the AVIF option in the dropdown when your browser doesn't support it.

When should I use WebP vs JPG?

WebP gives 25-35% smaller files at the same visual quality - so it's the better default for the web in 2024. JPG is the safer fallback when you need to support very old software (some print pipelines, ancient photo viewers). Both are lossy; PNG is lossless and ideal for screenshots, UI assets and anything with sharp text.

Is there a maximum file size?

Practically, anything under 50 MB works fine on a modern laptop. Beyond that, browser Canvas runs into memory limits - if the converter throws or hangs, your image is probably too large. Try cropping or resizing first.

Does the conversion preserve EXIF / metadata?

No - Canvas re-encodes from raw pixels, so EXIF (camera, GPS, timestamps), colour profiles and any embedded ICC are stripped. That's often what you want when sharing online (privacy) but can be a downside for archival photo work.

So funktioniert's

Drop an image
Drag from your file explorer onto the dropzone, or click to pick from disk.
Choose the output format
PNG (lossless), JPG (lossy, universal), WebP (smaller, modern), AVIF (smallest, Chrome/Edge only).
Tune the quality slider (lossy only)
Higher = larger file + more detail. 75-85 is a good default for photos.
Download
The converted file downloads with the new extension. The original isn't touched.

Was ist das?

An image converter changes a picture from one file format to another - typically to make it smaller (WebP, AVIF), more compatible (JPG), or to preserve transparency (PNG). The pixels themselves are decoded from the source format and re-encoded into the target; quality and file size depend on the target encoder and any lossy-compression settings.

Wann verwenden

Cutting page-weight for web images (PNG screenshots → WebP), preparing a photo for a service that only accepts JPG, stripping EXIF metadata before sharing a picture publicly, or converting an AVIF download you can't open in your usual photo app into a more compatible format.

Häufige Fehler

Converting a PNG screenshot to JPG and being surprised by colour banding around sharp edges - JPG is designed for photos, not for crisp UI. Picking 100% quality on JPG/WebP and getting almost no size reduction; the sweet spot is usually 75-85% quality. And forgetting that conversion strips EXIF - intentional for privacy, but unwanted when you need the camera data.
