PNG to JPG Converter
Convert
Transparent areas are filled with this color — JPG cannot store transparency.
The canvas previews the converted result live as you adjust the settings. Click Convert for the exact size and a before/after split — drag the divider to judge the quality, then download. The original file is never modified.
Your images are processed locally in your browser and never uploaded to any server.
Photos saved as PNG are needlessly huge. Converting to JPG typically cuts them by 80% or more. This tool handles the conversion locally, flattens any transparency onto a background color you choose (JPG does not support alpha), and processes whole batches at once.
PNG stores every pixel losslessly, which is wasteful for a photograph, where the eye cannot tell the difference between a lossless file and a well-compressed JPG anyway. A screenshot tool or a "save image as" that defaults to PNG can leave you with photos many times larger than they need to be, and this converter reclaims that space in one pass by handing the image to JPG's photographic compression.
How to use the png to jpg converter
- Add your PNG files.
- Pick a background color for transparent areas (white is default) and a quality level.
- Convert. Each file shows its dramatic size drop.
- Download individually or as a ZIP.
When a photo is stuck in PNG
This is the conversion for photographic content that ended up as PNG: camera shots, screenshots of photos, or images exported by a tool that defaulted to the format. At quality 80 the JPG is visually indistinguishable while shedding 80–95% of the size, which is a large, free saving on anything you store or upload in bulk.
Because JPG has no alpha channel, transparent areas are filled with a background colour you choose, white by default, so set it to suit the image. Keep PNG, though, for line art, logos, and text-heavy screenshots: JPG's compression smears sharp edges and flat colour, so those belong in PNG or WebP rather than here.
Frequently asked questions
What happens to transparent areas?
JPG cannot store transparency, so transparent pixels are filled with your chosen background color, white by default, which is right for most uses. If transparency matters, convert to WebP instead; it supports a full alpha channel at small sizes.
How much smaller will my files be?
For photographic content converted at quality 80, expect 80–95% size reduction. For flat-color graphics like logos the savings are smaller, and JPG's compression artifacts become visible. PNG or WebP suit those better.
When should I keep PNG instead?
Keep PNG for line art, text-heavy screenshots, logos, and anything needing transparency or pixel-exact reproduction. Switch photos and gradients to JPG or WebP.
