How to convert an image

  1. Drop your image onto the box above (or click / paste).
  2. Pick the target format — WebP, JPG or PNG — and adjust quality if you like.
  3. Click Download to save the converted image.

Everything happens locally with the browser's Canvas API: the image is decoded, drawn to an off-screen canvas, then re-encoded in the format you choose. Because the file never leaves your device, you can safely convert screenshots, client mockups, ID scans or anything else sensitive without it touching a server.

Which format should you use?

  • WebP — best all-round for the web: smallest files, supports transparency.
  • JPG — great for photos where you don't need transparency.
  • PNG — lossless, ideal for logos, icons, and graphics with sharp edges or transparency.

PNG vs JPG vs WebP at a glance

Each format makes a different trade between file size, fidelity and features. Use this table to pick the right target before you convert.

Format Compression Transparency Best for
WebP Lossy or lossless Yes (alpha) Modern websites, hero images, thumbnails
JPG Lossy No Photographs, email, wide compatibility
PNG Lossless Yes (alpha) Logos, icons, screenshots, line art

Common use cases

  • Speeding up a website — convert bulky PNG or JPG hero images to WebP to cut page weight by a quarter or more without visible quality loss.
  • Fixing compatibility — turn a WebP someone sent you back into JPG or PNG so it opens in older software, office tools or print workflows.
  • Preparing email and documents — flatten a transparent PNG to JPG when you need a solid background and a smaller attachment.
  • Cleaning up screenshots — keep crisp text and UI edges by exporting screenshots as PNG instead of a blurry JPG.

Tips & gotchas

  • Transparency is lost going to JPG. JPG cannot store an alpha channel, so transparent areas are filled with a solid background. Choose WebP or PNG if you need to keep transparency.
  • Don't re-compress repeatedly. Each lossy save (JPG or lossy WebP) discards a little more detail. Convert from the highest-quality original you have rather than from an already-compressed copy.
  • Quality 80–90 is the sweet spot. For most WebP and JPG photos, dropping below 100% saves significant size with no perceptible difference. The slider has no effect on PNG, which is always lossless.
  • EXIF and metadata are dropped. Canvas re-encoding strips embedded data such as camera info and GPS — handy for privacy, but keep an original if you need that metadata.

Frequently asked questions

Which formats can I convert between?
PNG, JPG/JPEG and WebP — the three formats that cover almost all web use. Pick your target in the Format dropdown.
What is WebP and should I use it?
WebP is a modern image format that is typically 25–35% smaller than JPG or PNG at the same quality, and every modern browser supports it. It is the best choice for fast websites.
Does converting PNG to JPG remove transparency?
Yes — JPG has no transparency, so transparent areas become white. If you need transparency, convert to PNG or WebP instead.
Is the converter private?
Completely. Conversion happens in your browser with the Canvas API; your image is never uploaded to a server.
Does the quality slider affect PNG output?
No. PNG is a lossless format, so the quality slider only applies when you export to JPG or WebP. Converting to PNG always preserves every pixel exactly, which is why PNG files are usually larger than the lossy alternatives.
Why does my converted file sometimes look the same size?
Re-encoding does not always shrink a file. A photo already saved as a well-optimised JPG may grow slightly when forced into PNG, and tiny images have little to gain. For the smallest results, choose WebP and lower the quality, or use our dedicated Image Compressor.
