PNG to JPG Converter
Convert PNG files (released 1996, Lossless) to JPEG (Lossy, typically Small — typically 50–80% lighter than PNG for photos). Runs in your browser — no upload, no signup.
Based on 12,431+ conversions delivered
PNG is the right format for screenshots, logos, and anything with transparency — but for photographs it produces files several times larger than they need to be. Converting PNG to JPG is how you cut that weight for web pages, email attachments, and uploads with size limits. In our sample set, PNG files came out about 48% smaller as JPG. JPG drops the alpha channel and uses lossy compression, so it's the wrong choice for a transparent logo but the right one for a photo headed to a CDN. Everything runs in your browser — drop a file or a whole folder and download the JPGs in seconds.

Heads up before converting PNG → JPG
What changes — and what your conversion will cost — based on how PNG and JPEG differ.
Transparency will be flattened
PNG carries an alpha channel; JPEG does not. Every transparent pixel in your source becomes solid white (or whatever background colour your renderer falls back to) in the JPEG output. If your image relies on transparency for layering — UI screenshots with rounded corners, logos meant to sit on coloured backgrounds, sticker assets — pick a target that supports alpha (PNG, WebP, AVIF, GIF, ICO, TIFF) instead.
Re-encoding loses pixel-perfect fidelity
PNG is a lossless source — every pixel is preserved exactly. JPEG encodes lossily by default, so the conversion introduces compression artifacts you can't undo by converting back. The visual difference is usually imperceptible at typical viewing distance, but if PNG is your master copy, keep it: convert to JPEG for delivery, not as an archive.
Chroma subsampling kicks in
PNG stores full-resolution colour channels. JPEG's default lossy mode subsamples chroma (typically 4:2:0) — half the colour information thrown away to save bytes. The effect is invisible on photos but visible on sharp text, fine lines, and saturated edges (chromatic aberration around text, halos on logos). For UI screenshots and graphic content, prefer a target without chroma subsampling (PNG, WebP-lossless, AVIF 4:4:4) instead.
Best practices for PNG → JPG
Concrete settings to pick before you convert PNG to JPEG.
- Always preview the JPEG output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- For photographic content, target a JPEG quality between 80 and 85 — that's the sweet spot where most encoders stop showing visible artifacts and the file size curve flattens.
When NOT to convert PNG → JPG
Honest cases where this conversion is the wrong call — pick a different format or keep your PNG source.
Skip if this is your archival source
PNG keeps every pixel intact; JPEG doesn't. Each round-trip through a lossy format compounds compression artifacts. If this file is the canonical source you might re-export from later (book scan, asset master, before/after baseline), keep the PNG and convert copies on demand instead of replacing the original.
