How to Convert JPG to PNG
Add the JPG files
Drop up to 30 files, .jpg or .jpeg, 25MB each. A file that is not a JPG still runs if this browser can decode it, and the row says so.
No quality slider
PNG has no quality number, and a JPG has no transparency to flatten, so those controls stay hidden.
Read the row
Each row shows the name, the size before the arrow, the size after it, and the pixel size. One failure does not stop the others.
Download
One finished PNG downloads by itself. Two or more download as a ZIP. photo.jpg becomes photo.png. A second file with the same name becomes photo-2.png.
Turn a JPG Into a PNG Without Sending the File
Jpg to png is the step when a photo, a screenshot, or a scan has to land in a program that asks for PNG. This jpg to png converter decodes the JPEG in this browser and writes a PNG here. The picture is not uploaded, and the download has no watermark. Up to 30 files, .jpg or .jpeg, can leave as one ZIP.
People convert a JPG to a PNG for three reasons. Later edits should be lossless: saving a JPEG again can add blockiness, and a PNG saved again keeps the pixels. A design app or an upload form accepts PNG and refuses JPG. A screenshot or a picture of text should keep the edges it already has. The JPEG article on Wikipedia describes the file you are leaving, and the Portable Network Graphics article on Wikipedia describes the PNG.
Convert jpg to png and the background stays opaque. A JPG has no alpha channel. Every pixel already has a color, including pixels that look like empty white. Those colors are copied. A white background stays white. The PNG is a copy of the decoded picture, not a cutout.
A cutout is a different job. The background remover makes a transparent PNG and uploads the picture. A logo that should already be transparent is the PNG maker. The reverse job is PNG to JPG. A WebP that should stay a PNG is WebP to PNG. A subject on a plain white field, which also uploads, is make background white.
Why Convert a JPG to a PNG
Use jpg to png when you are not done editing. After this page writes the PNG, later saves keep the same pixels. Another JPEG save can add blockiness.
Some design apps and upload forms list PNG and leave JPG off the list. Renaming photo.jpg to photo.png changes the name and leaves JPEG bytes. A program that reads the header still sees a JPEG. This page writes PNG bytes.
Screenshots and pictures of type have hard edges. A PNG keeps the edge the decoder already produced. It does not redraw a cleaner letter or erase a halo already in the JPG.
A White Background Stays White
People expect the white around a logo to vanish because the new file is a PNG. It stays. JPEG never stored a transparent pixel, so the PNG keeps that white. A checkerboard viewer still shows a filled rectangle.
When the subject needs an empty background, use the background remover or the PNG maker. Both upload the picture, because a cutout is a different tool. This page is only the format change, and the background color survives it.
Detail the JPG Already Lost Stays Lost
A JPEG is small because the camera, the phone, or the site already discarded detail. Convert jpg to png and those missing pieces are not waiting in the file. Block edges, blotches, and smeared gradients you can see in the JPG are still in the PNG. This page does not quote a percentage. The loss depends on how the JPG was saved, and this page does not measure it.
The download is not a denoise, a sharpen, or an upscale. Width and height match the decoded JPG.
Why the PNG Is Usually Much Larger
The file usually grows, often by a lot. That is normal. PNG stores the pixels without JPEG compression, so a detailed photo spends many more bytes. A flat graphic grows less than a busy photograph. The row is the measurement: the number before the arrow is the JPG, and the number after it is the PNG. This page states no percentage.
If the larger PNG is a problem, keep the JPG. WebP is the other format people pick when they want a file smaller than a PNG. This page does not write WebP.
EXIF, GPS, and Which Way Is Up
Phone photos often store the picture sideways and record the right way up in an EXIF orientation tag. This page decodes the JPG the way the browser decodes an image: that tag is applied, and the pixels are drawn upright. The width and height on the row are the upright size.
The PNG is a new file of those pixels. The original EXIF block is not copied. Camera model, GPS location, and the orientation tag are absent from the download. The picture is already turned. Keep the JPG beside the PNG if you still need the GPS or the camera name.
Before You Download the PNG
Check that you need PNG
If the next step only wanted a smaller file, keep the JPG. The row shows both sizes.
Expect the same background
White and every other background color stay. A transparent PNG is the background remover or the PNG maker, and those upload the picture.
Edit the PNG from here
Later PNG saves stay lossless. Keep the original JPG if you still want the smaller file or the EXIF.
Screenshots stay as sharp as the JPG
Halos already in the JPEG remain. The PNG stops another JPEG save from adding more.
What This JPG to PNG Page Does Not Do
The pictures are not uploaded. The download is a new PNG of the decoded pixels, not a renamed JPG.
- Up to 30 files, 25MB each. .jpg and .jpeg are the expected names.
- The PNG stays opaque. A white background stays white.
- Detail the JPEG already discarded is not restored. There is no percentage.
- The PNG is usually much larger. The row shows both sizes. This page does not write WebP.
- The browser turns the photo upright from the EXIF orientation. Camera model and GPS are not copied.
- Renaming .jpg to .png leaves JPEG bytes. A file this browser cannot decode errors on that row only.
- This page does not remove a background, sharpen, upscale, or add a watermark.
JPG, a Renamed File, and the PNG
| JPG you drop in | Renamed to .png | PNG from this page | |
|---|---|---|---|
| Bytes | JPEG | Still JPEG | PNG |
| Background | Opaque, including white | Unchanged JPEG | Same colors. White stays white |
| Detail | Whatever the JPG still has | Unchanged JPEG | The same decoded pixels. Nothing restored |
| File size | Small, because JPEG discarded data | Same as the JPG | Usually much larger. The row shows both |
| EXIF | May include camera, GPS, orientation | Still in the JPEG | Not copied. Pixels are already upright |
Changing the extension leaves a JPEG. This page writes a PNG and keeps the background.
JPG to PNG FAQ
Does jpg to png upload the file?
No. The PNG is built in this browser. Nothing is uploaded, and there is no watermark. One PNG downloads alone. More than one downloads as a ZIP.
Will the PNG be transparent?
No. JPG has no transparent pixels, so a white background stays white. To cut a subject out, use the background remover or the PNG maker. Those upload the picture.
Why convert a JPG to a PNG?
Later edits stay lossless, because another PNG save does not add JPEG damage. Some design apps and upload forms accept only PNG. Screenshots keep the edges the JPG already has.
Will a blurry JPG look sharper?
No. Convert jpg to png and you get the decoded pixels. Noise and lost detail stay. The page does not sharpen or give a percentage for the loss.
Why is the PNG so much bigger?
PNG stores pixels without JPEG compression, so a photo usually grows. Read both sizes on the row. If the size matters, keep the JPG. This page does not write WebP.
What happens to EXIF and a sideways photo?
The browser applies the EXIF orientation while it decodes, so the PNG is upright. Camera model and GPS are not copied. Keep the JPG if you still need those fields.
Can I convert a batch of JPG files?
Yes. Up to 30 files, 25MB each, .jpg or .jpeg. photo.jpg becomes photo.png. A second file with the same name becomes photo-2.png.
Convert JPG to PNG Here
Drop JPG files. They stay in the browser. The PNG keeps the same pixels, including a white background, and downloads with no watermark.
