How to use the jpg to png
To convert JPG to PNG, upload your file and download the result. No settings are needed. The conversion is lossless from this point forward, but it cannot restore detail the original JPEG already discarded. Expect the PNG to be three to six times larger.
- Add JPG filesDrop in one image or a batch of up to 20.
- ConvertConversion is automatic. A straight conversion needs no settings.
- Download PNGSave individually or as a ZIP archive.
About this tool
Converting JPG to PNG does not restore quality that JPEG already discarded. Those details are gone for good. What it does give you is a lossless container: from this point on, every further save is exact, and no new compression artefacts are introduced.
That makes the conversion worthwhile before editing, before adding transparency, or when a tool or platform specifically requires PNG. Expect the file to grow substantially, because PNG stores photographic detail far less efficiently than JPEG.
What you get
- Lossless PNG output with no further generation loss
- Batch conversion with ZIP download
- Optional resize during conversion
- Strips EXIF and GPS metadata
- Runs offline once the page has loaded
When to use the jpg to png
Before layered editing
Working in PNG means every intermediate save is exact. Editing and re-saving a JPEG repeatedly compounds artefacts with each generation.
When a platform rejects JPEG
Some upload forms, print templates and design tools accept only PNG.
Preparing to add transparency
PNG supports an alpha channel. Convert first, then use the Background Colour Changer to key out a flat background.
Rescuing a screenshot saved as JPG
Screenshots should never have been JPEG. Converting stops the artefacts spreading further, though the existing halos around text remain.
What to expect
| Source JPEG | Resulting PNG | Ratio |
|---|---|---|
| 500 KB photo, 12 MP | 4-6 MB | 8-12× |
| 200 KB photo, 2 MP | 1.5-2.5 MB | 8-12× |
| 150 KB screenshot | 200-400 KB | 1.5-3× |
| 80 KB logo or flat graphic | 40-120 KB | 0.5-1.5× |
| Text-heavy document scan | 1-3× larger | 1-3× |
How it works
JPEG and PNG solve opposite problems. JPEG models a photograph as smoothly varying frequencies and discards the ones your eye is least sensitive to. PNG stores every pixel exactly and relies on DEFLATE finding repeated patterns. Photographic noise has almost no repetition, which is precisely why PNG compresses it so poorly.
The conversion here decodes the JPEG to raw pixels and re-encodes them as PNG. Every pixel of the decoded image is preserved bit-for-bit, including the JPEG's compression artefacts, which are now part of the image data and are stored faithfully alongside everything else.
Converting does not clean anything up. It stops further degradation, which matters if the file will be edited and saved repeatedly, but it cannot undo what has already happened. There is no way to recover discarded frequency coefficients.
Common problems and how to fix them
- The PNG is enormous
- That is expected. A 500 KB photo commonly becomes a 4 MB PNG. If you do not specifically need PNG, WebP gives you lossless-looking quality at a fraction of the size.
- The PNG does not have a transparent background
- JPEG has no transparency to carry over, so the result is fully opaque. Use the Background Colour Changer to make a flat background transparent.
- The image still looks blocky
- Those artefacts were baked into the JPEG. Converting preserves them exactly; nothing can remove them.
- I wanted a smaller file, not a bigger one
- You want compression, not conversion. Use the Image Compressor, or convert to WebP instead.
Frequently asked questions
Will converting to PNG improve image quality?
No. Detail lost by the original JPEG compression cannot be recovered. Conversion prevents further loss; it does not undo past loss. If someone tells you converting to PNG "restores" quality, they are mistaken.
Why is the PNG so much larger than the JPG?
PNG is lossless and photographs contain enormous amounts of fine variation, which DEFLATE cannot compress well. A 500 KB JPEG commonly becomes a 3-5 MB PNG. That is expected, not a bug.
Does the PNG get a transparent background?
No. JPEG has no transparency to carry over, so the PNG is fully opaque. Use the Image Background Color Changer to make a flat background transparent.
When should I actually use this?
Before layered editing, when a platform rejects JPEG, when you need a lossless master for repeated saves, before transparency work, or when a screenshot or diagram was mistakenly saved as JPG and you want to stop the artefacts spreading. If none of those apply, keep the JPEG.
Is PNG better than JPG?
For screenshots, text, line art, logos and anything needing transparency, yes. For photographs, JPG or WebP is dramatically smaller with no visible difference. Neither is universally better.
Can I convert many JPGs at once?
Yes. Drop up to 20 files, press "Process all images" and download them as a single ZIP.
