Nothing is uploaded. Your files never leave this browser.
Converting PNG to JPG is a common task when you need very small file sizes. PNG (Portable Network Graphics) is a lossless raster format with a full alpha (transparency) channel. It reproduces sharp edges and text without compression artefacts, making it the default for logos, icons, UI assets and screenshots. JPG, on the other hand, gives you very small file sizes and universally supported. ZeroUpload performs this conversion entirely inside your browser, so your PNG file is never uploaded to a server.

When should you convert PNG to JPG?
You should convert PNG to JPG when you want photographs shared online or by email but your source is PNG. Typical situations include logos and brand assets that need a transparent background, screenshots where text must stay crisp, where the destination expects JPG instead.
PNG vs JPG
Portable Network Graphics (PNG)
PNG (Portable Network Graphics) is a lossless raster format with a full alpha (transparency) channel. It reproduces sharp edges and text without compression artefacts, making it the default for logos, icons, UI assets and screenshots.
Strengths
- + Lossless quality
- + Transparency (alpha) support
- + Great for sharp edges and text
Trade-offs
- – Larger files than JPG for photos
- – No animation
JPEG Image (JPG)
JPG (also written JPEG) is a lossy compressed format engineered for photographs. It discards detail the eye barely notices to produce far smaller files, and it is the most universally supported image format in existence.
Strengths
- + Very small file sizes
- + Universally supported
- + Ideal for photos
Trade-offs
- – Lossy — quality degrades on re-saves
- – No transparency
Expert guide: PNG to JPG
When PNG to JPG is the right move
PNG is brilliant for graphics, but it is the wrong tool for photographs. A photo saved as PNG can easily be 5–10× larger than the same photo as JPG, because PNG never throws away data. If you are emailing holiday photos, uploading to a website, or hitting an "image too large" limit, converting PNG to JPG is almost always the fix.
Watch out for transparency. PNG can have a transparent background; JPG cannot. When ZeroUpload converts a transparent PNG to JPG, those see-through areas are filled with white (the standard, expected behaviour) so you never end up with ugly black blocks.
Quality tip: JPG is lossy, so avoid repeatedly re-saving the same file as JPG. Convert once from your original PNG and keep that master.
