Image Converter

This converter re-encodes your image into the format you pick: JPG, PNG, or WebP. The pixel dimensions of the original are preserved — conversion changes the file format, not the size of the image.

JPG is best for photos and maximum compatibility. PNG is best when you need sharp edges or transparency. WebP is a modern format that is typically 25–35% smaller than an equivalent JPG and is supported by all current browsers.

One honest caveat: converting does not add information. Turning a JPG into a PNG will not restore transparency that was never there, and turning a small JPG into a large PNG just makes a bigger file with the same pixels.

The image is decoded in the browser and drawn onto a canvas, then re-encoded with the browser's native codec into the requested format at a high quality setting (92%).

Because the encoding runs in the browser, the tool inherits whatever codecs the device supports. All current browsers can encode JPG, PNG, and WebP; if a browser cannot encode a format, the tool will report that instead of producing a broken file.

The output file is generated in memory and offered as a download with the correct extension for the chosen format.

Each format has a different job. JPG uses lossy compression tuned for photographs and is the most widely supported format on the web. PNG uses lossless compression, which keeps text and edges perfectly sharp but makes files larger — often 5–10 times a JPG for the same photo. WebP is a modern format with both lossy and lossless modes plus transparency, and it typically beats JPG on file size at equal quality.

Conversion here is a re-encode, not a transcoding of the original data. That matters for two reasons: a re-encode is always slightly lossy (the new file is a fresh compression of the pixels), and a format change cannot recover data the source never had — a JPG's lost detail or a missing alpha channel cannot be recreated.

RAW camera files are not supported: this tool works with standard web formats only.
