Convert JPG to PNG Online
Turn lossy JPG photos into lossless PNG files without leaving your browser. PNG output keeps every pixel intact, supports transparency, and is ideal for logos, screenshots, and editing masters.
How to Convert JPG to PNG in Three Steps
Add one JPG or many, select PNG as the output format, then download lossless files individually or packed together as a ZIP.
Step 1
Add Your JPG
Drop a single JPG or select several files at once to start converting.
Step 2
Choose PNG
Select PNG as the output format, since encoding is lossless and needs no quality slider.
Step 3
Download PNG
Save your PNGs one by one, or download the whole set as a ZIP.
Why Convert JPG to PNG — Lossless Output For Logos, Screenshots And Editing
JPG and PNG were built around opposite priorities. JPG compresses photographs by permanently discarding visual data, which is why a camera photo stays small enough to share. PNG uses lossless DEFLATE compression and an optional eight-bit alpha channel, which is why it became the default for logos, icons, screenshots and anything with crisp edges. Understanding which job you are doing tells you which direction to convert.
This converter decodes your JPG with the browser’s native imaging engine, paints it onto a canvas, and re-encodes it as a PNG. Because PNG compression is lossless, the quality slider simply does not apply to PNG output and is ignored by the encoder. Every pixel the decoder produced is written out exactly. Pixel dimensions are preserved unless you deliberately enter a maximum width, and multiple files can be processed together and collected in one ZIP archive. Nothing is resampled, so the pixel grid you end up with is exactly the grid your JPG contained, just stored losslessly.
One expectation needs correcting before you start. Converting a JPG to PNG does not restore detail that JPEG compression already destroyed, and it does not make a low-quality photo sharper. What it does is stop the bleeding: from this point forward the file can be opened, edited and re-saved without accumulating further loss. It also gives you a format that supports transparency, which JPG structurally cannot. Expect the file to grow substantially, because lossless storage costs more space than lossy storage. A lossless master also matters whenever an image will pass through several tools, since every intermediate save stays pixel-exact instead of degrading a little at each step.
You should also know what this tool does not do. It preserves your image exactly as it looks, so it will not remove a background and will not turn a white or solid area into transparency. If that is your goal, pair this conversion with a dedicated background remover or a color-to-transparent tool. What you get here is a faithful, lossless PNG copy of the picture you already have.
Typical reasons to make the switch include needing a master file you can keep editing, preparing an image for design software that expects PNG, satisfying a submission system that whitelists only PNG, cleaning up documentation screenshots, and creating a file you can add transparency to later. Everything is processed locally in your browser, so sensitive photos, client work and identity documents never leave your device, and no watermark is added to any download. Batch output arrives as a single ZIP, so preparing a whole library for handoff stays a one-step job.
Lossless Output
PNG uses lossless compression, so re-saving never adds another round of JPG artifacts.
Alpha Ready
PNG supports a full 8-bit alpha channel that JPG simply cannot store.
Batch Conversion
Convert a whole folder of JPGs and download every PNG in one ZIP.
Local Processing
Your photos are decoded and re-encoded on your device, never on a server.
Original Dimensions
Width and height stay exactly the same unless you set a maximum width.
No Watermark
Downloaded PNGs are clean and unbranded, ready for client work.
FAQ
Frequently Asked Questions
PNG is lossless and supports transparency, making it better for logos, icons, screenshots, line art and any image you plan to edit further. JPG remains the better choice for photographs where file size matters, so the decision depends on what you intend to do next.
It does not restore detail that JPG compression already removed, and it will not sharpen a blurry photo. What it does is stop further quality loss, because every future save of a PNG preserves the pixels you have. Think of it as protecting the image rather than repairing it.
JPG discards data to stay small, while PNG stores every pixel exactly. A 160 kilobyte JPG can easily become a 600 kilobyte PNG because lossless encoding costs more space. The increase is normal and is the price of having a file that survives repeated editing.
No. The converter produces a faithful lossless copy of your image exactly as it looks, including its background. To remove a background or turn a solid color transparent, use a background remover or a dedicated color-to-transparency tool, then save the result as PNG.
The encoding step is entirely lossless, so no additional data is discarded beyond what the original JPG had already lost. The pixels written to the PNG are exactly the pixels the decoder produced from your JPG. The overall quality is therefore limited by the source file, not by this conversion.
Yes. Select or drag in as many JPG files as you need and they are all converted in the same run. Download each PNG individually, or export the complete set as one ZIP archive, which saves considerable time when preparing a batch of product or portfolio images.
No. Your JPG is read through the browser’s File API, decoded locally, drawn onto a canvas and encoded as PNG on your own machine. Nothing is transmitted to a server, nothing is stored after you close the tab, and no account is required to use the tool.
Yes. There is no registration, no email verification, no daily cap and no premium tier. Convert a single photo or an entire archive on the same terms. Output files are clean, with no watermark, badge or footer added to your image.
Stay with JPG for photographs, especially when upload size limits, page load speed or email attachments matter. JPG is dramatically smaller for photographic content, and the quality difference is invisible at sensible settings. Choose PNG only when you need lossless editing, transparency or crisp text and edges.
No. Renaming only changes the file name, not the encoded bytes – the image stays JPG data with a misleading .png label, and strict tools will reject or misrender it. A real conversion decodes the JPG and re-encodes those pixels as genuine PNG data.
