Took the photo on your phone and the marketplace won't accept it? You're probably uploading a HEIC (iPhone) or WebP file. Here's how to convert to JPG and get under the size limit.
Why your photo gets rejected
- HEIC is Apple's default photo format. It saves space on your phone but most marketplaces and many tools don't accept it.
- WebP is a modern web format — great for websites, but often rejected by sellers' upload forms.
- File too large. Many platforms cap uploads (often around a few MB). A high-res phone photo can easily exceed that.
How to fix it
- Upload your HEIC or WebP file (or a batch) to the Image Converter.
- Choose JPG as the output format.
- Pick a quality — "Balanced" is a good default; "Smaller file" if you're fighting an upload limit.
- Download. The tool shows how much smaller the file got.
JPG vs. PNG vs. WebP — which to pick
- JPG — smallest files, no transparency. The right choice for photos and marketplace uploads.
- PNG — lossless and supports transparency. Use it for cutouts (see the Background Remover) or graphics with sharp edges.
- WebP — small and supports transparency. Ideal for your own website; less so for marketplaces.
Reducing file size without wrecking quality
Dropping quality from 100 to ~80 usually cuts file size dramatically with no visible difference. If you also need exact dimensions for a marketplace, resize first with the Image Resizer, then convert.
