Image converter online (JPG, PNG and WebP)

How to convert an image

1. Choose your images or drag the files into the box. They are not sent to any server: everything happens in your browser.
2. Pick the output format: JPG, PNG or WebP.
3. If you pick JPG or WebP, adjust the quality. The lower it is, the smaller the file, with some loss of detail.
4. Check the size under "Before" and "After" and download. With several images, download everything in one ZIP.

JPG, PNG or WebP: which to choose

• JPG: the most compatible and, for photographs, usually light. It has no transparency: transparent areas become white.
• PNG: lossless and keeps transparency. Suited for logos, icons and graphics; for photographs the file is usually much heavier.
• WebP: usually smaller than JPG and PNG with a similar look, and supports transparency, but some older programs cannot open it.

What changes and what stays the same

The dimensions in pixels stay the same. What changes is how the image is stored: the format, the compression and, as a result, the file size.

Converting does not improve the image. A JPG converted to PNG gains no detail and no transparency: it is simply stored without further loss, and the file is usually larger.

When converting makes a difference

• Uploading a photo to a platform that only accepts JPG or PNG.
• Reducing the weight of product images by swapping PNG for JPG or WebP.
• Opening the image in a program that cannot read WebP or AVIF.
• Keeping the transparency of a logo by exporting it as PNG or WebP.

What this tool does not do

• It does not convert iPhone HEIC photos, GIF, SVG, BMP, TIFF or PDF: it accepts PNG, JPG, WebP and AVIF (AVIF depends on your browser being able to open it).
• It does not keep animations: the result is a still image.
• It does not upload the file to a server, so there is no sign-up or account limit: the limit is your device memory (up to 30 images at a time, 50 MB per file and 60 megapixels per image).
• It produces a new image, without the metadata of the original file (such as EXIF).
