Convert PNG to JPG

Shrink your PNG images by converting them to JPG: ideal for photos and screenshots to email or publish.

Or choose them, or paste an image (Ctrl + V or ⌘ + V).

Up to 20 files of 50 MB each (10 files of 30 MB on mobile).

The lower the quality, the smaller the file.

Longest side, proportions kept. Never enlarged.

Off by default to protect your privacy: a photo often contains the GPS location where it was taken, the camera model and the date. They are removed unless you tick this box.

    How does it work?

    PNG (Portable Network Graphics)

    PNG is a lossless format: every pixel is kept exactly. It supports transparency, making it the reference for logos, screenshots, diagrams and images containing text. For photos, however, it produces large files. It can be read everywhere.

    JPEG (Joint Photographic Experts Group)

    JPG (or JPEG) has been the universal photo format since the 1990s. Its lossy compression greatly reduces the size of photos by discarding barely visible details. It does not support transparency and degrades slightly with every re-save. Every device, program and website can read it.

    PNG or JPG: which format should you choose?

    Keep PNG for logos, diagrams, screenshots with text and any image with transparency: it renders flat colors and sharp edges without the slightest artifact.

    Switch to JPG for photos and images rich in gradients: at comparable visual quality, the file is often 3 to 10 times smaller, which makes emailing and publishing easier.

    How does the conversion work?

    1. Drop your PNG files in the area provided, choose them or paste an image: several files at once if you like.
    2. Adjust the options if needed: they apply to every file in the list, which are converted again automatically.
    3. Download each JPG file, or all of them at once in a ZIP archive.

    The conversion takes place in your browser. For your information:

    • The real format of each file is checked from its content, not its extension.
    • JPG does not support transparency: transparent areas become white.
    • The photo’s orientation is applied: the converted image displays the right way up everywhere.

    Examples

    Lightening photos exported as PNG

    A program exported your photos as PNG: 8.4 MB each at 3,000 × 2,000 px. Converted to JPG at quality 85, they weigh about 1.2 MB, or −85%, with no visible difference.

    Attaching screenshots to an email

    You need to send 10 PNG screenshots of 1.5 MB, 15 MB in total, beyond the limit of some email services. With quality 80 and a maximum size of 1,920 px, the ZIP archive of the 10 JPGs weighs about 3 MB.

    Frequently asked questions

    Why is my PNG image so large?

    PNG compresses losslessly: it is very efficient on flat colors, but much less so on a photo, where almost every pixel differs from its neighbor. JPG, which discards imperceptible details, then reduces the size dramatically.

    What happens to transparent areas?

    JPG does not support transparency: they are replaced with white. If you need to keep transparency in a light file, choose the PNG to WebP conversion instead.

    Will the text in my screenshots stay readable?

    Yes, as long as you keep a high quality (85 to 95). Below that, slight halos can appear around letters. For a screenshot that is mostly text, PNG is often still the best choice.

    What quality should I choose?

    85, the default value, is a good balance. Choose 90 to 95 for printing or archiving, 70 to 80 for a quick email or web publishing.

    Are my PNG files uploaded to a server?

    No. The conversion runs entirely in your browser, on your device: your files are never uploaded, stored or viewed by anyone. You can check this in the “Network” tab of your browser’s developer tools: no file appears there. By default, metadata (GPS location, camera, date) is also removed from the converted file; you can choose to keep it.
