Turn large PNG files into small, universally supported JPGs. Free in your browser — no sign-up, no watermarks.
How to convert PNG to JPG
- Click Choose files (or drag & drop) and select one or more PNG files. You can also paste an image from your clipboard.
- Adjust the quality slider if you want smaller files or maximum fidelity (92% is a good default).
- Press Convert to JPG. Each file is converted with a live progress indicator.
- Open the download page to save your files individually or grab everything as a single ZIP.
Why convert PNG to JPG?
PNG screenshots and exports are often 5–10× larger than they need to be. Converting to JPG shrinks them dramatically for email, forms with upload limits, and web use. Transparent areas are filled with a background color of your choice (white by default), since JPG does not support transparency.

What this tool preserves — and what it changes
✓ Preserved
- Pixel dimensions are untouched — flattening changes colors under transparency, never geometry
- The visible image at the quality you choose — the slider runs 50–100% and starts at 92%
↺ Changed
- Transparent areas are flattened onto the background color you pick with the color control — white by default (JPG has no alpha channel)
- The encode is lossy: hard graphic edges and text can show slight JPEG ringing at lower slider values
- PNG side data — text chunks and color-profile extras — is dropped as the pixels pass through the canvas
Known limits & edge cases
- Animated PNG (APNG) is read as its first frame; the inspection card warns that still-image tools use only the first frame
- Soft drop shadows blend into the chosen background color — pick the color the image will actually sit on
Engine: Your browser's own image decoder and canvas encoders (AVIF included); HEIC decodes via a bundled JavaScript decoder (Emscripten-compiled libheif); GIF, BMP and ICO are written by our own encoders.

Shrinking PNGs that were never meant to be PNGs
Cameras don’t produce PNGs, but scanners, screenshot tools and export dialogs often do — and a photographic image stored as PNG is enormous for no visible benefit. Converting to JPG typically shrinks such files by 80–90%, which is the difference between an email attachment that bounces and one that sends, or a form upload that fails its size limit and one that sails through.
Two things change in the conversion. First, compression becomes lossy — at the default quality (92) the difference is invisible for photos, and you can lower it further for drafts and previews. Second, transparency is flattened: JPG has no alpha channel, so any transparent region is filled with a solid white background. If the PNG is a logo or cutout whose transparency matters, convert it to WebP instead and keep the alpha.

Frequently asked questions
Is this PNG to JPG converter free?
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Can I convert multiple PNG files at once?
Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
Will I lose quality converting PNG to JPG?
JPG uses lossy compression, so there is a quality/size trade-off you control with the quality slider. At the default 92% the difference is practically invisible while files stay small. For archival-grade copies choose PNG instead.
