Why convert JPG to PNG
Most JPG to PNG conversions happen for one of three reasons: you need to edit the image and the editor wants a non-lossy source, you're working with a screenshot or logo where JPG's lossy compression is leaving visible artifacts around edges and text, or you want to stop accumulating quality loss across multiple re-saves during editing.
One thing worth being upfront about: converting JPG to PNG does not restore quality. Whatever compression damage is already in the JPG — blocky edges, color banding, soft details — gets locked into the PNG unchanged. PNG preserves the current state of the image perfectly; it cannot reverse-engineer information that was thrown away when the original was saved as JPG. If your source is a poor-quality JPG, the PNG will be a poor-quality PNG (just larger).
Everything runs locally: the JPG is decoded in the browser, re-encoded as PNG on your own device, and never uploaded. If you need to go the other direction or output WebP, our image format converter handles every direction.
Your files never leave your browser.
All processing runs locally on your device. No uploads, no tracking of file content.
FAQ
How do I convert JPG to PNG?
Drop your JPG file into the box above. PNG is already selected as the output, so just click convert and download. Drop several JPG files to convert them all at once.
Will converting JPG to PNG improve quality?
No, and this is the most common misconception. JPG is lossy — once compression artifacts (blocky edges, color banding, soft details) are baked into a JPG, they cannot be removed by converting to PNG. The PNG will perfectly preserve the JPG you fed in, artifacts and all. PNG locks in current quality; it does not restore lost quality.
Why is the PNG file much larger than the JPG?
Expect 3–10× larger, sometimes more. JPG uses lossy compression designed for photos and throws away data your eye barely notices. PNG is lossless — every pixel is preserved exactly, so files are bigger by design. This is normal, not a bug.
When does it actually make sense to convert JPG to PNG?
Three real cases: (1) you need to edit the image and add a transparent background (PNG supports transparency, JPG does not), (2) the image is a screenshot, logo, or contains text — PNG handles sharp edges and solid colors cleanly while JPG smears them, (3) you want to stop further quality loss because you'll re-save the file multiple times during editing (each JPG re-save loses more quality; PNG re-saves are lossless).
Does the converted PNG support transparency?
Technically yes — the PNG file format supports transparency — but the source JPG has no transparency to preserve, so the PNG will be fully opaque. To actually add transparent areas, open the PNG in an image editor (Photoshop, GIMP, Photopea) and remove the background there.
Are my JPG files uploaded anywhere?
No. The conversion runs entirely in your browser using the Canvas API. Your images never leave your device — check the Network tab if you want to confirm.
Is converting JPG to PNG free and unlimited?
Yes. No daily cap, no signup, no watermark. Convert as many JPG files to PNG as you like.
Can I convert multiple JPG files to PNG at once?
Yes. Drop as many JPG files as you want in one go. Each is converted and downloaded separately.
