Your file never leaves your device. Processed entirely in your browser.
Pick the background color in your JPG and it gets erased from the PNG output, leaving a transparent cutout. Works best on flat, solid-color backgrounds.

Why FileReadyNow
Convert JPG to PNG With Lossless Quality and Optional Transparency
PNG keeps every pixel intact, and the transparent background option goes a step further than a plain format swap.
Lossless Output
PNG does not recompress your image further. The pixels in the output match exactly what the JPG decoded to, with no extra artifacts added.
Transparent Background (Advanced)
Pick a background color and tolerance, and the tool erases it from the output PNG. Most converters only swap the format; this one can add transparency too.
Batch Conversion
Upload multiple JPG files and convert them all to PNG at once, with the same transparency settings applied across the batch.
Built for Editing Workflows
PNG is what most design tools, slide decks, and documentation systems expect for crisp logos, icons, and screenshots.
No Upload to Server
Conversion runs entirely in your browser. Your images are never sent to or stored on any external server.
No Account Required
Upload your JPG files and download the PNG results. No signup, no watermark, and no usage limits.
JPG was built for photos. It throws away detail your eye barely notices so the file stays small. That's fine until you need to re-edit, layer, or print the image, because every JPG you re-save adds a bit more compression on top of what's already there. Converting to PNG locks in the pixels you have right now and stops that from happening again.
The conversion happens right in your browser, so your files stay on your device and there's no limit on how many you convert.
How the transparent background feature works
Turn on "Make background transparent" and pick the color that matches your image's background. White and black cover most scans and screenshots, or you can use the color picker for anything else. The tolerance slider controls how close a pixel's color has to be before it counts as background. Keep it low and only near-exact matches get removed. Push it higher and it also clears the slight shading and JPG noise that often shows up around edges. This works best on logos, product shots, or anything with a flat, solid-color background. Photos with gradients or busy backgrounds will only get a partial cutout.
JPG in, PNG out
- Input: JPG files (.jpg, .jpeg)
- Output: PNG files (.png), lossless
- Optional: chosen background color removed and replaced with transparency
- Single files or batches both work
When JPG to PNG is the right choice
- Logos and product cutouts: use the transparency option to drop a flat background and get an asset that sits cleanly on any page or slide.
- Design and editing tools: PNG is the expected format for layering in tools like Figma, Photoshop, and Canva without re-encoding the image again.
- Screenshots and UI mockups: text and sharp edges in screenshots hold up better in PNG, since there is no further lossy recompression.
- Print and archival copies: converting before archiving avoids stacking more compression onto an image you might re-save multiple times.
- Documentation and slide decks: diagrams and exported charts saved as JPG often show ringing around text. PNG keeps the edges clean.
What to expect from the PNG output
Without the transparency option, the PNG is a pixel-for-pixel, lossless copy of what your JPG decoded to. No quality is lost in the conversion itself, though whatever compression artifacts were already baked into the JPG will still be visible. With the transparency option on, expect a clean cutout on flat backgrounds and a softer, partial result on backgrounds with gradients, shadows, or texture. The output works in every app, browser, and platform that supports PNG.

Frequently Asked Questions
Upload your JPG image, start the conversion process, and download the generated PNG file.
Many online converters provide free image conversion for standard usage requirements.
The conversion preserves the existing image quality, but it cannot recreate details that were already lost in the original JPG file.
JPG uses lossy compression for smaller file sizes, while PNG uses lossless compression for better quality preservation.
Yes. Most modern converters work on smartphones, tablets, laptops, and desktop computers.
PNG is often preferred for logos, screenshots, graphics, and images where maintaining quality is important.
