Click "Upload JPG" or drag your files directly onto the upload area. You can select multiple files at once if you're doing a batch conversion.
Your files are converted to PNG right away — no settings to fiddle with unless you want to. Single files are usually done in a second or two. Larger batches take a few seconds more.
Click "Download PNG" to save your file. If you converted multiple files, you can grab them all at once as a ZIP. No email, no account — just download and you're done.
PNG supports alpha channel transparency, so your image can have see-through areas that blend into any background. This is what makes it the go-to format for logos, icons, and UI assets.
PNG is lossless — every pixel is stored exactly. You can open, edit, and re-save without the gradual quality degradation that happens with JPG.
PNG is supported by every browser, operating system, and image editor in common use today. Your converted files will open without issues on any device.
Unlike JPG, which loses a little quality each time you save, PNG can be edited indefinitely without accumulating compression artifacts. It's the right format for ongoing design work.
Upload up to 10 JPG files at once and convert them all in a single go. Useful for processing design assets, photo sets, or whole folders without doing them one at a time.
The converter is completely free. No watermarks are added, no account is required, and there's no limit on how many files you can convert.
JPG doesn't support transparent backgrounds — any clear area just turns white. If you need to place an image on a colored background, overlay it on a design, or use it as a logo without a box around it, you need PNG. Converting to PNG first unlocks the alpha channel, which is what makes those clean, edge-to-edge overlays possible in Figma, Photoshop, Canva, and other design tools.
Every time you save a JPG, it recompresses — and that adds up. After a few rounds of editing, you'll start seeing blurry edges and color banding. Converting to PNG before your editing workflow means you can save as many times as you like without any of that degradation. Most designers keep a PNG working file and only export to JPG at the very end.
For anything going to print or into long-term storage, PNG is the safer choice. It's lossless, meaning the file you archive today will look exactly the same in five years. Print shops and publishers prefer it because there's no risk of recompression artifacts creeping in between file handoffs.
Nothing to install. The converter works directly in your browser on any device — desktop, tablet, or phone. Just open the page and start converting.
Convert up to 10 JPG files to PNG in one session. Files are processed in parallel, and you can download them individually or as a single ZIP archive.
Files up to 50 MB are supported, which covers high-resolution photos, detailed graphics, and most professional-use images without any issues.
Adjust PNG compression level to balance file size and encoding speed. You can preview the output before committing to a conversion.
All transfers use HTTPS encryption. Files are deleted from servers immediately after conversion — we never store, view, or share your images. GDPR compliant.
The interface works on all modern mobile browsers. Convert files from your phone or tablet without needing to install any app.
JPG and PNG are both widely used image formats, but they're built for different jobs. Knowing the difference helps you pick the right one — and know when converting makes sense.

Convert JPG to PNG when you need a transparent background, plan to edit the image multiple times, or need a lossless file for print or archiving.
Converting a JPG to PNG comes up more often than you'd think — whether you need a transparent background for a logo, want to edit an image without gradual quality loss, or just need a format that plays well with design tools. JPG is great for photos. PNG is better for graphics, logos, UI assets, and anything you're going to edit or layer. Understanding when to use each one makes the decision easy.
The two most common reasons are transparency and quality. JPG doesn't support transparent backgrounds at all — any see-through area becomes solid white. If you've ever pasted a logo onto a design and ended up with an ugly white box around it, that's the JPG transparency problem. PNG solves it cleanly.
The other reason is editing. JPG uses lossy compression, which means every save introduces a small amount of quality loss. That's usually fine for a finished photo, but if you're going through multiple rounds of editing, it adds up fast. PNG preserves every pixel exactly, so it doesn't degrade over time. That makes it the standard working format in most design workflows — you edit in PNG, then export to JPG or WebP for delivery.
For archiving and print work, PNG is also the safer choice. It's a guarantee that the file won't quietly lose quality between handoffs.
**Compression:** JPG is lossy — it discards some data to keep file sizes small. PNG is lossless — nothing is thrown away, which keeps quality perfect but makes files larger. For photos where file size matters, JPG wins. For logos, screenshots, and graphics, PNG is the better call.
**Transparency:** JPG has no transparency support. PNG does, via its alpha channel. This is the deciding factor for logos, overlays, stickers, and UI assets.
**File size:** JPG files are generally smaller, which is why it's still the dominant format for photography and social media. PNG files are larger but don't carry the compression artifacts that show up in JPG at lower quality settings.
**Color:** Both support 24-bit color (16.7 million colors). PNG's 32-bit RGBA mode adds the alpha channel for transparency. For most use cases, color depth isn't the deciding factor — transparency and compression type are.
A few things worth knowing before you convert:
**Keep your original JPG.** The conversion to PNG won't improve quality — it preserves what's already there. If your source JPG is heavily compressed, the PNG output will preserve those artifacts too. Always hold onto originals.
**PNG compression level doesn't affect quality.** Unlike JPG quality settings, PNG compression only controls file size and encoding speed — not image sharpness. A higher compression level means a smaller file, but it takes longer to encode. Level 6 is a reasonable default for most uses.
**Think about your end use.** If you're converting for a design workflow, lossless PNG is the right call. If you're prepping images for a website, you might want to go to WebP instead for better compression at comparable quality.
**Check the output.** After converting a batch, open a few files to make sure they look right before deleting your originals.
**Designers** need it constantly — logos, icons, and UI assets almost always need transparent backgrounds, and PNG is how you get there. If you've received a JPG logo from a client, converting to PNG is usually the first step.
**Developers** use PNG for web graphics, app icons, and anything that needs to sit cleanly on different background colors. It also comes up in image processing pipelines where lossless intermediate files are preferable.
**Photographers and content creators** move between formats depending on the platform — JPG for social, PNG for graphics and overlays, WebP for web-optimized delivery. Having a reliable converter in your workflow saves time.
**Anyone editing images repeatedly** benefits from switching to PNG early in the process to avoid quality loss stacking up across saves.
If you need a transparent background, plan to keep editing your image, or just need a reliable lossless format, converting to PNG is the right move. PortImg's converter handles the process in seconds, directly in your browser — no software to install, no account to create, and no watermarks on the output.
