Convert JPG to PNG in seconds. Remove white backgrounds from logos and signatures.
Last updated:
Your original JPG files are never changed. Each PNG keeps the same name, with .png instead of .jpg.
Convert JPG images to PNG instantly in your browser. PNG supports transparent backgrounds and is the preferred format for logos, icons, signatures and graphics.
No file is uploaded to any server. The conversion happens entirely on your device, so it works fast even on mobile data.
JPG is great for photos, but it has limits. Convert to PNG when you need one of these:
JPG cannot store transparency, so a logo saved as JPG always has a white box around it. Choose Remove white in the tool to turn that background transparent.
The live preview shows transparent areas as grey checks. If a white halo remains around the edges, move the Strength slider up a little. If parts of your logo disappear, move it down.
Keep white inside the logo is ticked by default, so only the background connected to the edges is removed. White letters or shapes inside the design stay solid.
Need your signature on a PDF, Word document, offer letter or invoice? Sign with a dark pen on plain white paper and take a photo in daylight, with no shadow from your phone.
Upload it and choose Signature. The paper becomes transparent, the ink turns crisp black or blue, and the image is cropped to just your signature.
For government exam forms that ask for a signature in JPG under a size limit, use the Signature Resizer instead. It crops, whitens the paper and saves the exact KB.
No. A PNG keeps exactly the quality your JPG already has. It cannot bring back detail that JPG compression has already removed.
What PNG does is stop any further loss. If you plan to edit an image many times, crop it, add text or reuse it in designs, PNG is the safer format.
PNG is lossless, so it stores every pixel exactly. A PNG of a photo is often 3 to 8 times larger than the JPG. Logos and graphics with flat colours stay much smaller.
If you need a small file to share, keep the JPG. Read when to use PNG vs JPG for the full picture.
Both formats have their own strengths. Here is when to use each one.
| Feature | JPG | PNG |
|---|---|---|
| Compression | Lossy, smaller files | Lossless, larger files |
| Transparency | Not supported | Supported |
| Photos | Best format | Works, but big files |
| Logos and icons | White box around them | Best format |
| Signatures on documents | White box shows | Clean, transparent |
| Editing many times | Loses quality each save | No loss |
| WhatsApp and email | Fast, small files | Slower, larger files |
Going the other way? Use the PNG to JPG converter to make files smaller for WhatsApp and forms.
Need an exact size like 3.5×4.5 cm or 200×230 px? Use the passport size photo resizer. To put several images into one document, use JPG to PDF.
Everything you need to know about this JPG to PNG converter at a glance
Upload your JPG files or paste an image, choose whether to keep or remove the background, then tap Convert to PNG for Free and download. It is free, with no signup and no watermark.
Yes, 100% free. There are no paid plans, no signup and no watermark, and you can use it as many times as you like.
No. PNG keeps exactly the quality your JPG already has, but it cannot bring back detail the JPG lost. The benefit is that the PNG will not lose any more quality when you edit and save it again.
PNG is lossless, so it stores every pixel instead of compressing the photo like JPG does. A PNG of a photo is often 3 to 8 times bigger. That is normal and does not mean anything went wrong.
Yes. Choose Remove background before converting. It works best for logos, icons, text and products on a plain white or single-colour background. The preview shows the transparent areas as a grey checked pattern.
Sign on plain white paper, take a clear photo in good light, upload it and choose Signature. The paper becomes transparent, the ink turns crisp black or blue, and the image is cropped to the signature.
Not by default. Keep white inside the logo is ticked, so only the background connected to the edges is removed. Untick it if you also want white areas inside the design removed.
Not well. This tool removes plain, single-colour backgrounds. A busy background, such as a room or outdoors, needs an AI background remover. Converting to PNG on its own keeps the photo exactly as it is.
Yes. Add up to 10 images, convert them together, then download each PNG or all of them in one ZIP file.
Open this page in Chrome or Safari, tap Choose JPG Files, pick your images from the gallery, then tap Convert. The PNG saves to your phone, with no app needed.
No. Everything happens inside your browser, so your images are never uploaded or stored anywhere. ToolsFlow cannot see your files.
Yes. JPG and JPEG are the same format with a different file extension. This tool converts both, and also WebP images, to PNG.
Yes. The width and height in pixels stay exactly the same. The only exception is Signature mode, which crops away the empty paper around your signature.
No watermark is ever added. The PNG is still your own image, so you can use it anywhere, including for business, websites and printing.
