What converting JPG to PNG can and cannot do
PNG is lossless: once your image is a PNG, editing and saving it again will not add any more blur or blocky artefacts. That is why designers convert photos to PNG before working on them.
- It does not restore quality. Detail lost when the JPG was first saved is gone; PNG simply stops further loss.
- Files get bigger, often 3 to 10 times for photos, because PNG stores every pixel exactly.
- No automatic transparency. A JPG has no transparent areas, so the background stays solid in the PNG until you remove it in an editor.
For sharing or uploading, the opposite direction is usually better: PNG to JPG makes files much smaller. To read text from a converted screenshot, try Image to Text (OCR).

When to use it
Design work
Use images in tools that prefer PNG. For sharing, PNG to JPG goes the other way and saves space.
Editing
Avoid adding more JPG artefacts with each save. Cut out the part you need with Crop Image before editing.
Documents
Insert PNGs into slides and reports. Make the PNG smaller in pixels with Resize Image.
Website requirements
Meet upload rules that ask for PNG. Read text from a screenshot with Image to Text (OCR).

Frequently asked questions
Are my images uploaded to a server?
No. The JPG is decoded and saved as PNG by your own browser, so the photo is never sent anywhere.
Will converting to PNG improve quality?
No. It keeps the current quality and stops further loss when you edit and save again, but it cannot restore detail already lost in the JPG.
Why is the PNG bigger than the JPG?
PNG is lossless and does not throw away detail, so photos become larger files. That is normal.
Will the background become transparent?
No. JPG has no transparency, so the PNG has the same background. To remove a background, you need a background remover.
Can I convert PNG back to JPG?
Yes. Use our PNG to JPG converter.
How are the new files named?
Each file keeps its original name with the new extension, so you can match it to the original easily.
Is there a limit on file size or number?
No fixed limit. Large batches of big photos take a little longer on older phones.
Is PNG better than JPG?
PNG is better for screenshots, text, logos and images you will edit again. JPG is better for photos you want to share, because files are much smaller.
Can I convert JPG to PNG on my phone?
Yes. Pick the photos from your gallery and the PNG files download to your phone.
Why is the PNG so much bigger than my JPG?
PNG stores every pixel exactly, while JPG throws away detail you are unlikely to notice. For photos that usually makes the PNG 3 to 10 times larger.
How this tool works. These image tools run entirely in your browser using the Canvas API built into every modern browser, the open-source libheif decoder for iPhone HEIC photos and Tesseract, a widely used open-source OCR engine, for reading text. Each tool is tested with real phone photos, screenshots and scans before it goes live, and nothing you open is sent to a server.
