JPEG, PNG, and WebP: choosing an image format
There is no single best image format for every job. Choose based on the kind of image, whether transparency is needed, the target platform’s accepted formats, and how much compression artifacts matter.
Quick comparison
| Format | Often useful for | Watch for |
|---|---|---|
| JPEG | Photographs and complex gradients | Repeated lossy saves can soften detail |
| PNG | Transparency, interface graphics, crisp edges | Files can be large for photographs |
| WebP | Web delivery with efficient compression | Check the destination’s accepted formats |
Export workflow
- Start from the highest-quality original available.
- Resize to the required dimensions before compression.
- Export a test version and inspect fine text, edges, and gradients.
- Compare file size against visual quality.
- Keep an original copy in case the asset needs to be revised.
For ad uploads, always check the current platform specifications rather than assuming a format is accepted everywhere.
Worked example: choosing an export for a product image
A photographic product image often works well as a compressed JPEG or WebP, while a logo with transparent areas generally needs PNG or another format that preserves transparency. Compare the exported file visually at its actual display size; the smallest file is not automatically the best if text edges or product details become visibly damaged.
Prepare the asset with the Social Image Resizer and check placement dimensions in the social image sizing guide.
