PNG to JPG Converter
Image Tools
Convert PNG images to JPG with a configurable background color and quality slider. Big savings for photographic PNGs.
Runs entirely in your browserAbout PNG to JPG Converter
PNG is great for graphics and screenshots, but it's drastically inefficient for photographs — a PNG of a photo can be 5–10× the size of a comparable JPG with no visible quality difference. Converting photographic PNGs to JPG is one of the easiest wins for page weight or storage savings.
This converter handles the one tricky case: PNG supports transparency, JPG doesn't. When you convert, anywhere the PNG was transparent must be filled with a solid color — by default we use white (the safe choice that matches most pages), but you can pick any color via the color picker. The quality slider (20–100%) controls JPG compression; 80–90% is usually indistinguishable from the original at much smaller size. Conversion runs in your browser via the Canvas API; the original PNG never leaves your machine.

Why does it ask for a background color?+
JPG doesn't support transparency. Anywhere the PNG was transparent must be filled with a solid color in the JPG output. White matches most webpages; pick black or another color for special cases.
What quality should I pick?+
For photos: 80–90% is usually indistinguishable from the original. For screenshots with sharp text and crisp lines, go higher (92–98%) — JPG can struggle with high-contrast edges.
Will I lose quality?+
JPG is lossy, so yes — some information is discarded. For photographs the loss is invisible at high quality. For graphics with sharp edges and flat colors, you may see compression artifacts; in that case, keep the PNG.
When should I NOT convert PNG to JPG?+
If transparency matters (logo overlays, partially transparent UI assets), if the image has very sharp edges (line art, pixel art, screenshots of UI), or if you'll edit the image again later.
Is my image uploaded anywhere?+
No. Conversion is local via Canvas.
