What this does
Converts PNG images to JPG with an adjustable quality slider. Everything runs in your browser — drop up to 20 files, convert, download. No upload, no account.
Why convert PNG to JPG?
Size, almost always. PNG stores every pixel losslessly, which makes photographs and screenshots enormous — a full-screen capture can be 3–8 MB as PNG and 300 KB as JPG with no visible difference. Common reasons to convert:
- An upload form rejects your file for being over its size limit.
- Email attachments that would otherwise bounce or crawl.
- Web pages where a heavyweight PNG is slowing the load.
What quality setting should I use?
- 92 (default) — visually indistinguishable from the original for nearly everything.
- 80–90 — the sweet spot for screenshots and photos headed to the web; big savings, no obvious artifacts.
- Below 70 — visible compression around text and sharp edges; only for thumbnails.
What happens to transparency?
JPG doesn't support transparency, so transparent regions of your PNG are flattened during conversion. If your image relies on a transparent background (logos, stickers, UI assets), convert to WebP instead — it compresses nearly as well as JPG and keeps the alpha channel.
Will text in screenshots stay readable?
At quality 85+, yes. JPG's weakness is sharp, high-contrast edges — exactly what text is — so avoid dropping below ~80 for screenshots of code or documents. If the screenshot must stay pixel-perfect, it's a case for keeping PNG and using the image compressor instead.
Is my data private?
Yes — the conversion is done by your browser's canvas API on your device. No image data is sent anywhere.
