What's the difference between PDF and WebP?

PDF is the universal document format. WebP is Google's modern image format.

What quality should I pick?

For WebP, quality 75-85 is the sweet spot — small files with no visible difference from the original. Lower than 60 starts to show artifacts. Higher than 90 mostly just makes the file bigger.

Why convert away from PDF?

PDF is the universal document format. Where it falls down: anywhere you need to edit the content after the fact (PDFs are read-mostly); single images that don't need pagination (use the image format directly). WebP addresses that for most workflows.

When is WebP the right format?

WebP is a good choice for: web images of any kind — the modern default; replacing both JPG photos and PNG screenshots on a single site; animated images that would otherwise be GIFs (much smaller). It is a poor choice when print pipelines and pre-2020 software (use PNG/JPG for compatibility).

Anything surprising about PDF or WebP?

Browsers can render PDFs in-page — no plugin required since around 2015. And on the WebP side: webP lossless is competitive with PNG and often smaller. Worth trying.

Does this work on mobile?

Yes. The drop zone falls back to your phone's file picker, and conversions run on-device just like desktop. Large files may be slower on mobile due to CPU and memory constraints, but the workflow is identical.

What's the maximum file size?

No hard limit — the browser handles it. Files under 50MB convert in a few seconds. Larger files work but may take longer as the browser allocates memory. If you hit issues, batch in smaller groups.
