About JPG to PNG
People usually want JPG to PNG for one of three reasons: a website, app or template takes PNG only; an editing job is ahead and each save shouldn’t chip away at the picture; or they hope PNG will make a blurry JPG sharper. The first two are sound. The third, unfortunately, is not.
A JPG discards fine detail the moment it is saved, and that information is gone from the file. PNG is lossless, meaning it stores whatever pixels it receives exactly, including any blockiness, color banding or fuzzy edges the JPG compression introduced. The result is a perfect copy of the JPG as it stands, not a restoration. Nor does the format change remove a background: a white backdrop stays a white, fully opaque backdrop.
The conversion itself takes place in this tab. Your browser decodes each JPG and turns it upright according to its orientation tag, and those pixels go into a new PNG file. There’s no quality slider, because PNG has nothing to give up; the only setting that alters the pixels is an optional max size (1280, 1920, 2560 or 4096 px along the longer side). IMG_2231.jpg comes out as IMG_2231.png.
How to use JPG to PNG
- Add the JPG or JPEG filesDrop images onto the converter, browse for them, add a folder together with its subfolders, or paste a copied picture. Both .jpg and .jpeg names work, up to 500 files per run.
- Keep the full size, or cap itFor editing, leave Original size selected so every pixel is there. Choose a smaller long edge only to meet an upload limit. Then decide whether photo info should come along, with or without the GPS position.
- Download the PNG versionsGrab each file from its row, or press Download all (ZIP) for the full set. Names that clash within a batch get a “ (2)” suffix, so no result overwrites another one.
When people use it
A working copy for a long retouching session
Cropping, color correction and layered edits often mean saving the same file many times. Repeated JPG saves compound their losses; a PNG working copy survives every save unchanged, and a final JPG is exported once at the end.
Uploaders and templates that insist on PNG
Some uploaders, site builders and game modding tools check the file type and refuse anything but PNG. A converted copy passes that check, and the picture looks exactly as it did before.
Marking up a photo with labels and arrows
Adding callouts, arrows or highlight boxes to a photo for a manual or bug report? Do the markup on a PNG and the new lettering and lines stay crisp, because they never pass through JPEG compression when you save.
What PNG adds, and what it doesn’t
| Expectation | What actually happens |
|---|---|
| A sharper, clearer picture | No change: the PNG shows exactly what the JPG showed |
| A transparent background | No: every pixel stays opaque until you cut the subject out in an editor |
| No further loss while editing | Yes: re-saving a PNG never degrades it |
| Acceptance where only PNG is allowed | Yes: it is a genuine PNG file, not a renamed JPG |
| A smaller file | No: expect it to be several times larger |
Why the PNG weighs several times more
JPG achieves its small size by throwing information away, and PNG declines to throw anything away. A photo has texture, sensor noise and gradients in nearly every pixel, which lossless compression can’t squeeze much, so a PNG copy of a typical camera photo is several times the size of the JPG. When the file has to stay manageable, reducing the dimensions helps most: a 1920 px cap on a photo 4000 px wide removes roughly three quarters of its pixels.
EXIF, orientation and color
Date taken, camera model, exposure settings and GPS coordinates are copied by default into the PNG’s eXIf chunk, which is defined in the W3C PNG specification. Some older photo managers skip that chunk, so a converted file can look undated there even though the information is present.
Since the pixels are already upright, the orientation tag is set back to its default value. If the PNG is going to strangers, Remove GPS location takes out the coordinates alone; clearing Keep photo info produces a file with no EXIF whatsoever. Colors are converted to standard sRGB while the JPG is decoded.
Situations where JPG to PNG is the wrong move
- Fixing a blurry or pixelated JPG. A format change can’t help here; only a better original can.
- Getting a transparent logo. Removing a background is editing work, and the converter hands back the same opaque picture.
- Needing a vector file. A PNG is still a grid of pixels and turns blocky when enlarged.
- Using an editor that already exports PNG. Saving as PNG from there does the same job.
Each run tops out at 500 files, and huge photos are limited by how much memory your device has, which favors a laptop or desktop over a phone for big jobs. On iPhone, iPad and Mac, Safari has to be version 16.4 or newer; recent Chrome, Edge and Firefox builds are fine everywhere. To combine photos into one document instead, see JPG to PDF. Your JPGs never leave the device; see how to verify that.
