Frequently Asked Questions

Everything you need to know about Image Compressor (WebP/AVIF)

How much can I shrink an image without visible quality loss?

WebP at 80% quality typically drops file size 60–80% compared to a JPG original, with no perceptible difference for web/social use. AVIF is even better — often 50–70% smaller than WebP at the same visual quality. For print or product photography, stay above 90% quality.

Should I use WebP, AVIF, or JPEG?

WebP is the best default — every modern browser supports it. AVIF gives ~30% smaller files but encoding is slower and Safari support arrived only recently. JPEG is the universal fallback. PNG is lossless — use only for screenshots, logos, or images with transparency.

Are my images uploaded to your server?

No. Compression uses the HTML5 Canvas API entirely in your browser. You can verify by opening the network tab — there are zero outbound requests after page load. Safe for client work, NDA photos, and personal files.

Why does the file size sometimes get bigger after compression?

If your input is already heavily compressed (e.g. a JPEG saved at 50% quality) and you set quality higher (90%), re-encoding adds overhead. Set quality at or below the original. Also: PNGs converted to JPEG/WebP at high quality may grow because PNG is lossless and JPEG/WebP add chroma data.

What's the max number of images I can compress at once?

20 per batch — to keep your browser responsive. For larger volumes, run the tool multiple times or use the same workflow with a desktop app like Squoosh CLI.
