AVIF
Good at
- Compresses tighter than WebP — usually another 20–30 %
- Handles 10 bits per channel and high dynamic range
- Transparency and animation are both there
Awkward about
- Noticeably slower to encode than the others
- Support outside browsers is still thin
- On small images it sometimes loses to WebP on size
Use it when
- Large images on a site where weight matters
- When you have a fallback for older browsers
Good at
- Looks the same everywhere: fonts, margins and line breaks are fixed
- The one format any office will accept without argument
- Holds text, vectors and photographs in a single file
Awkward about
- Hard to edit: it is a format for reading, not for changing
- Weight depends on what is inside — a scanned page can weigh as much as a book
- Text inside a scan stays a picture until something recognises it
Use it when
- The document is being sent, printed or filed somewhere official
- The layout must not shift on someone else’s device
- Loose pages need to become one file
Common questions
- Does the file get uploaded to a server?
- No. AVIF → PDF runs right in your browser and the file never leaves your device. It only goes to a server if the browser cannot cope — and then we delete it within a couple of hours.
- Will transparency survive?
- Yes, PDF supports transparency, so semi-transparent edges stay as they were.
- Can I get the original quality back afterwards?
- Nothing is lost, but nothing is gained either. PDF stores exactly what AVIF hands over, including the gaps AVIF left behind when it compressed. No tool can bring those back, and the file grows several times over. This conversion makes sense for editing, not for quality.
- How many files, and how large?
- Up to 50 files at a time, 50 MB each. No sign-up, no watermarks.
