Compress Image (Keep Quality)
Reduce file size using efficient, high-quality encoding — with no forced target and no resizing. Dimensions always stay exactly the same, and photographic images are re-encoded at a visually-lossless setting. This is the tool to use when a smaller file matters more than hitting an exact KB or MB number.
This tool never resizes your image and never forces a target file size. It re-encodes at a high-quality setting (visually lossless for photos) so the file is smaller without a noticeable difference. PNGs with transparency stay fully lossless.

How this differs from our target-size tools
Our compress-to-KB tools search for the smallest quality and dimensions that still fit a specific number, which can mean visible trade-offs on very tight targets. This tool skips that search entirely: it always keeps full dimensions and uses one high, visually-lossless quality setting, so you get a smaller file with no perceptible change.
Honest about lossy vs. lossless
JPEG and WebP are lossy formats — re-encoding at 92% quality is visually indistinguishable from the source for virtually all photos, but it is not mathematically identical to the original bytes. PNGs with transparency are re-compressed losslessly, meaning the pixel data is unchanged.
When to use a target-size tool instead
If a form or portal requires a specific maximum file size (like 100 KB), use one of our compress-to-size tools instead — they're built to hit an exact number, even if that occasionally means a visible trade-off.
Tips for the best result
- Use this tool as your default for everyday compression — it's the safest choice when quality matters most.
- Already-optimized JPEGs may only shrink a little, since there's less inefficiency left to remove.
- For transparent PNGs, savings are typically smaller since the format stays lossless.
Frequently Asked Questions
Will this noticeably change how my image looks?+
No. Photographic JPEG/WebP output uses a 92% quality setting, which is visually lossless for virtually all real-world photos. PNGs with transparency are recompressed losslessly.
Does it resize my image?+
Never. Dimensions are always preserved exactly — this tool only changes encoding efficiency, not pixel count.
Is my image uploaded anywhere?+
No, everything happens locally in your browser using the Canvas API.
Why is my file barely smaller?+
If your source image was already efficiently encoded (e.g. exported from professional software), there may be little redundant data left to remove — that's expected, not a bug.
