Image Converter

Pick a format, then choose or drop your images. They are converted on your device and never uploaded.

Convert to
90%

Lower quality gives smaller files. 80–90% is a good balance for photos.

JPG has no transparency: transparent areas become white.

Runs in your browser. Nothing you enter is sent to a server.

How it works

Your browser decodes each image, draws it on an invisible canvas and saves it again in the format you choose. The work happens in a background thread, so the page stays responsive even with large photos. Images are converted one at a time to keep memory use low on phones.

Images up to 50 MB are accepted. Pictures larger than 16.7 megapixels (4096 × 4096) are scaled down to that size, because that is the largest image some browsers, including Safari on iPhone, can process. The result tells you when this happens.

Which format should I use?

Format Best for Transparency Compression
JPG Photos, sharing, email, compatibility with everything No Lossy: small files, some detail lost
PNG Screenshots, logos, text, graphics with flat colours Yes Lossless: exact pixels, larger files
WebP Websites and apps Yes Lossy here: usually smaller than JPG at similar quality

Google’s own measurements found lossy WebP files 25–34% smaller than JPG files of comparable quality. All current browsers display WebP, but some older desktop software cannot open it; convert to JPG when in doubt.

Quality setting

For JPG and WebP, the quality slider trades file size against detail:

  • 90–100%: visually identical to the original, large files.
  • 75–85%: the usual choice for photos on the web; differences are hard to see.
  • Below 60%: noticeably blurry or blocky, especially around text and edges.

PNG is always lossless, so it has no quality setting. Converting a photo to PNG usually makes it much larger without improving it; PNG only helps with graphics, screenshots or when you need transparency.

Frequently asked questions

Are my images uploaded to a server?

No. The conversion runs inside your browser, so your photos never leave your device. That also makes it fast, because there is nothing to upload or download except the result you save.

How do I convert WebP to JPG?

Select JPG, then choose or drop your WebP files. Each one is converted as soon as it is added; press Download to save it.

Why is my JPG larger than the original?

Converting a small or heavily compressed image to a higher quality setting can make it bigger. Lower the quality slider (80–90% works well for photos), or keep the original format.

What happens to transparent backgrounds?

PNG and WebP keep transparency. JPG does not support it, so transparent areas are filled with white.

Is the photo's location and camera data kept?

No. Converting creates a new image from the pixels only, so EXIF metadata such as GPS location, camera model and date is removed. The photo's rotation is applied first, so it still looks the right way up.

Can I convert HEIC photos from an iPhone?

Not yet. HEIC needs a separate decoder that browsers do not include. On an iPhone you can set Settings → Camera → Formats → Most Compatible to take photos as JPG.
