PNG to JPG

How to convert PNG to JPG

1. Add PNGs. Drop one file or a whole batch onto the box above — up to 200 images (100 MB) per batch.
2. Choose the background. JPG cannot store transparency, so pick what transparent pixels become: white by default, or any colour you like. A live preview shows the flattening before you convert.
3. Set quality and optionally resize. 85% is a good default for photos; screenshots usually want 90% or higher. You can also cap the longest edge to downsize.
4. Compare and save. Every card shows before/after sizes with the exact difference. Open the comparison view to judge quality, then download individually or take the whole batch as a ZIP.

When JPG is the right (or wrong) choice

• Photos: JPG is ideal — the converted file is typically much smaller than the original PNG.
• Screenshots, logos, flat graphics: PNG is usually smaller and sharper. This tool converts anyway and tells you honestly when the JPG came out larger.
• Need transparency kept? Then JPG is the wrong target — stay with PNG, or try WebP in the Image Compressor.

Limitations, stated plainly

• Transparency is always flattened. JPG has no alpha channel; the original PNG file is never modified — the flattening only happens in the copy you download.
• JPEG artefacts are possible at low quality — the comparison view lets you judge before saving.
• Batch size is capped (200 files, 50 MB each, 100 MB total) and sources beyond 24 megapixels / 8192 px per side are refused, so very large images fail early with a clear message instead of freezing your device.
• Metadata is not copied. PNG text chunks and colour profiles beyond what the browser reads are not preserved in the JPG.
