Image Converter

JPG, PNG and WebP, converted on your own machine.

Every tool runs entirely in your browser. Your files are never uploaded to a server.

This converter changes images between JPG, PNG and WebP entirely inside your browser. Drop files in, pick a format, and download the result. Nothing is uploaded to a server, so there is no queue, no file limit imposed by us, and no watermark.

How to use the Image Converter

  1. Add your images. Drag files onto the drop zone, or click it to browse. You can add several at once.
  2. Choose the output format. Pick JPG, PNG or WebP, then set quality and an optional resize.
  3. Convert and download. Press Convert. Save files individually, or take the whole batch as a ZIP.

About image formats

The three formats here solve different problems and are not interchangeable. JPG is lossy: it discards detail the eye is poor at noticing, which is why a photograph shrinks so dramatically, and why re-saving the same JPG repeatedly degrades it a little each time. PNG is lossless and supports full alpha transparency, making it correct for screenshots, logos, diagrams and anything with hard edges or flat colour, but wasteful for photographs where it can easily be five times the size of an equivalent JPG. WebP was designed to replace both, offering lossy and lossless modes plus transparency, and typically lands 25 to 35 percent smaller than JPG at matched visual quality. Its only real drawback is age: very old software may not open it. A practical rule is to convert photographs to JPG or WebP, keep anything with transparency or sharp edges as PNG or WebP, and avoid repeatedly re-encoding lossy formats. Because conversion here runs through your browser rather than a server, quality settings apply immediately and nothing you drop in is retained anywhere.

Frequently asked questions

Are my images uploaded anywhere?
No. Decoding and re-encoding happen in your browser using its own image codecs. You can confirm this by opening your network inspector while converting — no request is made.
Which format should I choose?
JPG for photographs you want small. PNG when you need transparency or exact pixels, such as screenshots and logos. WebP when you want both, and every browser you care about is modern.
Why did my transparent image get a white background?
JPG has no transparency channel, so transparent pixels must become something. We flatten to white. Convert to PNG or WebP instead to keep transparency.
Does converting remove EXIF data?
Yes, by default. Re-encoding drops EXIF as a side effect, which removes GPS coordinates, camera serial numbers and timestamps before you share the file.
Can it read HEIC photos from my iPhone?
Not yet in most browsers, which cannot decode HEIC natively. Safari on Apple devices can. A dedicated HEIC converter is on the way.
