JPG to PNG
Converting a .jpg image to .png re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .jpg image to .png re-encodes the pixels for a different balance of size, quality, and support. A .jpg file is a photograph or other continuous-tone image compressed with the JPEG standard, the most widely used image codec ever shipped. Nearly every camera, phone, and website produces or accepts .jpg files, which makes it the default interchange format for photos.
A .png file is a losslessly compressed raster image with full 8-bit alpha transparency, making it the standard choice for graphics that must stay pixel-perfect. Screenshots, logos, UI assets, and diagrams are the classic .png territory, since sharp edges and flat color survive without compression artifacts. For this route the practical draw is perfectly lossless, so files can be opened and re-saved indefinitely and true 8-bit (or 16-bit) alpha channel — balanced against photographic content produces files several times larger than JPEG or WebP, which is worth knowing before you commit a large batch.
Why convert JPG to PNG?
The honest use for this route is not quality recovery — JPG's losses are permanent — but format requirements: an app that only accepts PNG, a workflow that needs lossless intermediate files so repeated saves stop degrading the image, or a design tool that expects PNG input before adding transparency. The conversion itself is exact: every pixel the JPG decodes to is carried into the PNG unchanged, and no further generation loss can accumulate from this point on.
JPG vs PNG at a glance
| Aspect | JPEG image (.jpg) | PNG image (.png) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded | uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth) |
| Strongest at | publishing photographs on websites where file size and universal support matter | screenshots and screen recordings exported as stills |
| Weak spot | every re-save re-compresses the image, so quality erodes across editing generations | photographic content produces files several times larger than JPEG or WebP |
| Metadata | carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails | text metadata lives in tEXt/iTXt chunks and XMP can be embedded there; standardized EXIF arrived late via the 2017 eXIf chunk, so many tools still drop EXIF when writing PNG |
Pick PNG as the output
Select .png in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if PNG is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid PNG file. Outputs keep the original filename with the .png extension.
JPG to PNG questions, answered
Will converting JPG to PNG lose quality?
No new loss is introduced — since jpg is lossy-oriented and png is lossless-oriented, everything the .jpg file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .png does not "restore" quality.
Is it private to convert JPG files here?
Yes — the .jpg file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the PNG file work?
Every modern browser has rendered PNG with full alpha since Internet Explorer 7 fixed its transparency bug in 2006, and native OS support is universal on Windows, macOS, Linux, iOS, and Android. It is also the required format in many contexts, such as iOS app icons and favicon fallbacks.
Will the PNG file be bigger or smaller than my JPG?
Larger, sometimes much larger. A lossless .png must store every pixel or sample the decoder produced, without the perceptual shortcuts .jpg used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my JPG file?
In .jpg, carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert PNG back to JPG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .jpg → .png → .jpg is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
