Why convert JPG to PNG?
JPG doesn't support transparency, a dealbreaker for logos, product images on white backgrounds, and any graphic that needs to be layered in design tools. Converting JPG to PNG also stops further compression loss, giving you a clean base for editing, documentation, or any workflow where quality matters more than file size.
- Add transparency support, essential for logos, product images, and design overlays
- Stop further compression loss every time you edit and re-save
- Lossless output preserves every detail for further editing in Photoshop or Figma
- Batch convert hundreds of JPG files to PNG in one go
- All processing happens locally on your Mac, files never leave your device
- Drag and drop from Finder or any folder on your Mac
JPG vs PNG file sizes
| File type | JPG | PNG | Saved |
|---|---|---|---|
| Product photo (12MP) | 1.8 MB | 6.2 MB | Larger, lossless quality |
| Website banner (1920×600) | 320 KB | 1.1 MB | Larger, no further loss |
| Social media image (1080×1080) | 450 KB | 1.8 MB | Larger, transparency ready |
When to convert JPG to PNG
Creating product images with transparent backgrounds
E-commerce product photos need transparent backgrounds for marketplace listings and website product cards. Convert JPG to PNG first, then remove the background in your editor.
Preserving quality for graphic design workflows
Importing JPG into Photoshop or Figma and re-saving repeatedly causes generation loss. Convert to PNG once to stop the quality degradation cycle.
Screenshots and documentation images
Technical documentation and UI screenshots need crisp text. Once in PNG, further edits and re-saves won't blur the edges again.
Logo and brand asset archival
If you only have JPG versions of logos or brand assets, convert to PNG for a lossless archival format that supports transparency for future use.

How do I convert JPG to PNG on Mac?
Open Picmal, drag your JPG files into the window, select PNG as the output format, and click Convert. Picmal preserves all details from the original JPG in a lossless PNG file.
Does converting JPG to PNG improve image quality?
Converting JPG to PNG won't recover quality already lost to JPG compression, but it prevents further degradation. The PNG output is lossless, so no additional quality is lost during conversion or future edits.
Will PNG files be larger than the original JPG?
Yes. PNG uses lossless compression, so files are typically 3-5x larger than JPG. A 500KB JPG photo might become 1.5-2.5MB as PNG, in exchange for zero new compression artifacts and transparency support.
Can I add a transparent background after converting to PNG?
The conversion itself won't add transparency, but once in PNG format you can remove backgrounds in Photoshop, Figma, or any editor that supports alpha channels. JPG doesn't support this at all.
When should I use JPG to PNG vs keep JPG?
Convert to PNG when you need transparency, will edit the image further, or need pixel-perfect quality for screenshots and graphics. Keep JPG for photos you're just sharing or uploading to the web.
