Image Format Converter

Convert an image between PNG, JPG, and WebP without installing anything. Drop in a file, choose the output format, adjust quality for the lossy formats, and download the converted image. Everything runs on your device using the browser canvas, so your pictures are never uploaded to a server.

Which format should you choose?

Each format has a job. PNG is lossless and supports transparency, making it right for logos, icons, screenshots, and anything with sharp edges or text — but files are larger. JPG is lossy and excels at photographs, where its compression shrinks files dramatically with little visible loss, though it can't do transparency. WebP is the modern all-rounder: it usually produces smaller files than both JPG and PNG at the same visual quality and supports transparency too, which is why it's become a web default. Convert photos to JPG or WebP to save space, and keep graphics with transparency as PNG or WebP.

Quality and transparency notes

The quality slider applies to the lossy formats, JPG and WebP — lower quality means a smaller file with more compression artefacts, so nudge it down until you can just start to notice a difference, then step back. It has no effect on PNG, which is always lossless. One thing to watch: converting a transparent PNG to JPG will fill the transparent areas, usually with white or black, because JPG has no transparency. If you need to keep a see-through background, convert to WebP or keep it as PNG. This tool shows the resulting file size so you can see the trade-off immediately.

Choosing formats for the web versus print

Where an image will be used should guide the format. For the web, smaller files load faster and help your page's performance, so WebP or a well-compressed JPG is usually right for photos, with PNG or WebP reserved for graphics that need crisp edges or transparency. For print or archiving, file size matters less than quality, so a lossless PNG (or the original) preserves every detail. Converting a photo to WebP before uploading it to a site can noticeably cut its weight with no visible loss, while keeping a PNG master ensures you always have a pristine copy to work from later.

PNG, JPG, or WebP?

The right format depends on the picture. JPG compresses photographs well and is the safe default for anything with smooth gradients, at the cost of some detail. PNG is lossless and supports transparency, which makes it right for logos, screenshots, and graphics with sharp edges or flat color. WebP is the modern option, usually producing smaller files than either at similar quality and now supported by every major browser. A common workflow is to keep a PNG master and export a WebP or JPG for the web — converting locally here means you can try each and compare the result without uploading anything.
