How to Convert PNG, JPG, and WebP Online
Marketplaces and design tools often require a specific format—JPG for Amazon hero images, PNG for transparent assets, WebP for modern storefronts. FreeMake converts up to ten files at once in your browser with no upload, so listing errors from wrong extensions disappear before you publish.
Upload images in the current format
Add PNG, JPG, or WebP files to the left panel—up to ten per batch. Sellers migrating from supplier ZIPs or design exports frequently need a quick format fix without opening desktop software.
Pick the output format you need
Choose JPG for photo listings, PNG when you need transparency, or WebP for your own site. The workbench shows each file so you can set the right target per image when formats differ in one batch.
Preview color and sharpness
JPG export applies compression; check edges and brand colors before download. Converting PNG to JPG removes transparency—confirm backgrounds are acceptable for marketplace white-bg rules.
Download or ZIP all conversions
Save individual files or export a ZIP for bulk upload to Seller Central or Shopify. iPhone HEIC sources should use the HEIC converter first, then convert here if another format is required.
Why Format Conversion Matters for Sellers
Wrong formats cause instant upload failures, broken transparency, and bloated pages. Local conversion keeps catalog assets private while you standardize files across channels.
Fix platform rejection errors fast
Some stores accept only JPG or PNG for main images. Converting in-browser avoids reshooting or re-exporting from heavy design apps.
Optimize for web vs marketplace
Use WebP on your DTC site for speed, JPG on Amazon for compliance. One supplier photo can branch into channel-specific formats in minutes.
No cloud upload of product IP
Conversion runs locally—unreleased SKUs and wholesale imagery stay on your machine, unlike many online converters that require server upload.

When to Use PNG, JPG, or WebP
JPG is the default for product photography on Amazon, eBay, and most marketplaces—smaller files with acceptable quality for photo-heavy listings. PNG preserves transparency for overlays, badges, and graphics composited in design tools.
WebP delivers smaller files at similar visual quality for Shopify themes and custom storefronts when your CDN supports it. Always verify each channel's latest media guidelines before switching primary listing formats.
- JPG — hero images, lifestyle shots, bulk catalog photos
- PNG — logos, icons, cutouts with transparent backgrounds
- WebP — site speed on modern browsers; not always accepted for marketplace uploads
- HEIC — convert iPhone photos via HEIC tool before using this converter
