Convert 500 images at once — free and private
Most online converters limit you to one image at a time or charge for batch operations. This tool processes every file you drop using the browser's Canvas API — JPEG/WebP encoding happens on your machine, no subscription needed. The resulting ZIP preserves your original filenames with a new extension so nothing gets lost.
FAQs
How many images can I convert at once?
No hard cap — 500 typical JPEG/PNG files work comfortably. Very large files may require splitting into smaller batches depending on your device's RAM.
Are my originals changed?
No. Converted copies are written to a ZIP; your originals on disk are never touched.
Does converting to WebP reduce quality?
Quality defaults to 92 — visually indistinguishable from the original for most photos, yet ~30% smaller than JPEG.
Can I convert transparent PNGs to WebP?
Yes. WebP fully supports transparent alpha channels while offering significantly smaller file sizes than PNG.
