What this tool does

Converts an image between PNG, JPEG, and WEBP directly in your browser — drop in a file, pick a target format, and download the result. Nothing is uploaded to a server at any point; decoding, redrawing, and re-encoding all happen locally using the same Canvas API every browser already ships with.

How to use it

  1. Choose or drop an image — PNG, JPEG, WEBP, GIF, or BMP are all accepted as input.
  2. Pick a target format.
  3. For JPEG or WEBP, adjust the quality slider if you want a different size/quality balance.
  4. Download the converted result.

Converting to and from each format

JPG to PNG, or PNG to JPG

Converting JPG to PNG doesn't recover any detail lost in the original JPEG compression — it just re-encodes losslessly from that point forward, so the file is usually larger with no quality gain. Converting PNG to JPG is the more common direction, useful for shrinking a photo's file size when you don't need transparency.

JPG or PNG to WEBP

WEBP typically produces a meaningfully smaller file than either JPEG or PNG at comparable visual quality, and unlike JPEG it can preserve transparency — worth trying by default unless you specifically need one of the older formats for compatibility with a system that doesn't support WEBP.

A note on quality settings

The quality slider only affects JPEG and WEBP, since both are lossy formats with an adjustable compression level. PNG is lossless — there's no quality trade-off to make, only a fixed, larger file size in exchange for pixel-perfect reproduction.

Questions

Is this Image Converter free?

Yes, completely, with no signup and no limit on how many images you convert.

Is my image uploaded anywhere?

No. The conversion happens entirely in your browser using the Canvas API — the image is decoded, redrawn, and re-encoded on your own device. Nothing is sent to a server; you can confirm this yourself by watching your browser's Network tab while using the tool.

Will converting to JPEG lose transparency?

Yes — JPEG has no concept of transparency, so any transparent areas in a PNG become solid white (or whichever color you choose) once converted. If you need to keep transparency, convert to WEBP instead, which supports it while still compressing better than PNG in most cases.

Will my photo's orientation come out wrong?

No — this loads your image the same way a browser normally displays it (through a standard image element), which already applies any orientation correction from the file's metadata. The exported image matches what you see in the preview.

What's the actual difference between PNG, JPEG, and WEBP?

PNG is lossless and supports transparency — best for screenshots, logos, and graphics with sharp edges or text. JPEG is lossy and much smaller for photos, but has no transparency and can show compression artifacts at low quality. WEBP is newer, supports both lossy and lossless modes plus transparency, and generally beats both of the others on file size at a given quality — worth defaulting to unless you specifically need PNG or JPEG for compatibility.
