Multi-Format Image Export — Free, Fast & Private

Modern responsive image markup serves the best format the browser supports — AVIF if available, WebP for older browsers, JPG as universal fallback, plus PNG when you need lossless. Generating all four formats per image used to mean running four separate compressors. MiniPx Pro generates them in one pass, in your browser.

Use case: drop a 4 MB product photo. Toggle the “Also export as” panel: AVIF + WebP + JPG + PNG. Compress. Get up to 5 files — the format you picked, plus one copy per ticked format — or up to 17 if you also enable responsive sizes. Each variant is optimally encoded for its format — AVIF gets the smallest size, WebP balances size and compatibility, JPG handles every browser ever shipped, and PNG stays lossless for flat graphics.

The output ZIP names files per the Pro rename pattern (e.g. photo-1280w.webp, photo-1280w.avif) so dropping into <source> tags is straight copy-paste.

See it in action on the main compressor. The free tier outputs one format per input; Pro adds the multi-format toggle.

How it works

  1. Get Pro: From /pricing/ ($3.24/mo or $59 lifetime).
  2. Open the main compressor: Visit minipx.com/.
  3. Enable the Also export as panel: In Pro Tools, tick the formats you want — AVIF, WebP, JPG (and PNG if needed). These are saved in addition to the format chosen in the Format control, not instead of it.
  4. Compress: Each input produces one output per format. Download as ZIP.

Frequently asked questions

Why generate AVIF + WebP + JPG + PNG instead of just AVIF?
Browser support. AVIF works on Chrome 85+, Firefox 93+, Safari 16+. WebP covers older browsers (95%+ today). JPG is universal. For production sites you need all three to use the <picture> element with format-based source selection.
Are the formats encoded with the same quality?
Same input quality setting, but the actual file size differs because each codec has different compression efficiency. AVIF is smallest, JPG is largest, WebP is in between.
Can I pick per-format quality?
Yes. The Advanced Codec panel takes a quality override per format, and it applies to every output in that format, the primary included. Leave a format blank and it follows the main quality setting.
Does this work for HEIC inputs?
Yes — HEIC is decoded then re-encoded into your chosen format(s). Common iPhone workflow: HEIC in, JPG + WebP out.
