- Click Convert. We decode the JPG and re-encode it as a lossless PNG.
- Download the PNG. It opens in every image viewer and editor — and survives further edits without losing quality.
Why convert JPEG to PNG
Honest note up front: converting JPG to PNG will not add transparency. JPG never had a transparent background, and the conversion cannot guess where 'background' is. If you wanted to turn a white background into transparency, you need a background-removal tool, not a format converter.
That said, there are legitimate reasons to convert JPG to PNG. The biggest one is locking in lossless quality before further editing. Every time you re-save a JPG, it gets slightly worse. Re-saving a PNG never degrades quality. If you plan to edit a JPG repeatedly, convert to PNG first.
PNG is also the format some platforms or CMSs require — a handful of design tools, older publishing systems, and print workflows insist on PNG. Converting once gets you compliant.
If you genuinely wanted to add transparency, the workflow is: convert to PNG, then open in an image editor and erase the background. Or use a background-removal tool, which exports as PNG with transparency built in.
Common use cases
- Lock in lossless quality before editing a JPG repeatedly (each JPG re-save introduces small losses).
- Upload to a CMS or platform that requires PNG specifically.
- Prepare an image for a workflow that will later add transparency (you still need a separate background-removal step).
- Send a photo to a designer who prefers PNG for compositing.
- Archive a JPG in a lossless container for long-term storage.
Tips for best results
- PNG does not add transparency to a JPG. The white background stays white unless you remove it manually in an editor.
- The PNG will be significantly larger than the JPG — often 5-10x for photographs. PNG is lossless, JPG is compressed.
- If you want a smaller image or a transparent background, JPG to PNG is probably the wrong choice. For transparency, use a background remover; for smaller size, stay with JPG.
- EXIF metadata is generally preserved in the conversion. Strip it in the JPG first if you want a clean PNG.
- Quality already lost in the JPG cannot be recovered by converting to PNG. The PNG preserves whatever the JPG already had.
About JPG
JPG (JPEG) is the most widely used image format in the world, designed in 1992 specifically for photographs. It uses lossy compression to discard small visual details the eye does not notice, producing dramatically smaller files than uncompressed formats. JPG is universally supported but does not store transparency, and each re-save introduces small additional losses.
About PNG
PNG (Portable Network Graphics) was created in 1996 as a free alternative to GIF. It uses lossless compression — every pixel preserved exactly — and supports transparency with smooth alpha blending. PNG is the standard for screenshots, logos, icons, and any image where pixel-perfect quality matters. It is universally supported by every browser, OS, and editor.
JPG vs PNG
| Property | JPG | PNG |
|---|---|---|
| Lossless quality | No (lossy) | Yes |
| Supports transparency | No | Yes (but won't add to JPG) |
| File size | Small | 5-10x larger |
| Quality after repeated editing | Degrades | Stays exact |
| Best for photographs | Yes | Overkill |
| Best for logos / icons | No | Yes |
| Universal app support | Yes | Yes |
Privacy and safety
Your JPG is uploaded over HTTPS, processed in an isolated job, and deleted from our servers within one hour — along with the converted PNG. We never train models on your images, never share them, and never require an account.
Frequently asked questions
Will the PNG have a transparent background?+
No — converting cannot add transparency. The JPG has no transparency information, so the PNG will have the same solid background. To remove a background, use a background-removal tool before or after conversion.
Will I gain quality by converting JPG to PNG?+
No. Quality already lost in the JPG cannot be recovered. PNG preserves whatever the JPG had, no more. The benefit is preventing future quality loss in edits, not improving the current image.
Why is the PNG so much larger than the JPG?+
PNG is lossless and stores every pixel exactly. JPG discards data to shrink the file. For a photograph, the PNG can easily be 5-10x larger.
Is the JPG to PNG converter free?+
Yes. 5 conversions per day as a guest, 10 per day signed in with Google. No credit card.
When does it make sense to convert JPG to PNG?+
Before repeated editing (to avoid cumulative JPG losses), for platforms that require PNG specifically, or for archival lossless storage. For sharing, emailing, or uploading photos, JPG is usually the better choice.
Is it safe to upload my JPG?+
Yes. Files are uploaded over HTTPS and deleted from our servers within one hour. We never train models on your images.
Does it work on Mac, Windows, iPhone, and Android?+
Yes. The converter runs in any modern browser. The PNG output works on every platform.
Can I convert several JPGs at once?+
Yes — sign in with Google and use the batch uploader. You get a single ZIP of PNGs.
