Why convert WebP to PNG?
WebP is built for the web, but many desktop editors, print tools, and older apps still won't open it, and when you need guaranteed lossless quality or a clean alpha channel for editing, PNG is the safe choice. Converting WebP to PNG gives you a universally editable, lossless file with transparency intact.
- Lossless PNG output, no further compression artifacts introduced
- Preserves transparency (alpha channel) from WebP
- Opens in every editor: Photoshop, Figma, Affinity, Preview, and more
- Batch convert entire folders of WebP files at once
- All processing happens locally on your Mac, files never leave your device
WebP vs PNG file sizes
| File type | WebP | PNG | Saved |
|---|---|---|---|
| Web graphic with transparency | 180 KB | 640 KB | Larger, lossless & editable |
| Downloaded WebP photo (1920×1080) | 320 KB | 1.4 MB | Larger, no further loss |
| Icon / logo (transparent) | 28 KB | 74 KB | Larger, transparency intact |
When to convert WebP to PNG
Editing web images in Photoshop or Figma
Many design tools won't import WebP. Convert to PNG first so you can edit downloaded or exported web images without compatibility errors.
Preparing images for print
Print workflows expect PNG or TIFF, not WebP. Convert WebP to PNG to hand off lossless files to a print service.
Keeping transparency for layered work
When you need a clean alpha channel for compositing, PNG is the reliable, widely supported choice.
Archiving web assets losslessly
For assets you'll re-edit later, PNG avoids the generation loss that comes from repeatedly re-saving lossy WebP.

How do I convert WebP to PNG on Mac?
Open Picmal, drag your WebP files into the window, select PNG as the output format, and click Convert. The output is lossless and preserves any transparency.
Does converting WebP to PNG improve quality?
It won't recover detail a lossy WebP already discarded, but PNG is lossless, so from that point on there's no further quality degradation, which matters when you'll edit or re-export the image.
Is transparency preserved when converting WebP to PNG?
Yes. Both WebP and PNG support alpha-channel transparency, so transparent areas in your WebP files carry over cleanly to PNG.
Will PNG files be larger than the original WebP?
Usually yes. PNG is lossless while WebP is highly compressed, so a 200KB WebP might become 600KB–1MB as PNG. In return, it opens in any editor and loses nothing more.
Why convert WebP to PNG instead of JPG?
Choose PNG when you need lossless quality, transparency, or sharp edges for graphics and screenshots. Choose JPG when you want the smallest file for sharing photos and don't need transparency.
