YOUR IMAGES. ON YOUR DEVICE.

Compress image

Make a JPG or WebP smaller with quality controls or a maximum size target. PNG can be re-encoded, but has no quality slider and may not shrink.

Local processing · No uploads · No saved drafts

Choose your image

Still JPG, PNG or WebP. Originals up to 100 MiB and 100 megapixels each (32,768 pixels per side). Up to 5 files, 200 MiB total; processed one at a time.

Choose images

Your original files stay unchanged.

Choose the result

Output format

PNG re-encoding is lossless at the canvas stage; a quality slider does not optimise PNG. JPG and WebP quality changes can lose detail.

Maximum file size

We search for the highest quality within the target. Dimensions never shrink automatically.

Output dimensions

Large originals are welcome. Choose a smaller export when needed; your original stays unchanged. Exports use up to 12.5 megapixels and 12,000 pixels per side.

Advanced settings

Quality 82%

Used for JPG and WebP. A size target searches quality instead. PNG does not use this setting.

Re-encode even if the original meets the target, to remove camera and location metadata.

A few things to know

Private by design

Selected files, filenames and results stay in this tab. There are no image uploads, tracking scripts or saved drafts here. Clear removes the app’s references; closing the tab also discards the workspace. Your browser and downloaded files remain under your control.

Honest image quality

New exports remove camera and location metadata after applying rotation. Images are rendered to an 8-bit sRGB canvas using your browser’s colour handling. Exact ICC, wide-gamut and HDR fidelity is not promised. JPG-to-PNG cannot restore lost detail. An unchanged original keeps its metadata.

Supported in this release

Still JPG, PNG and WebP only. Animation, SVG, HEIC/HEIF, AVIF and 16-bit PNG are rejected. JPEGs with extra embedded pictures can be exported as the main picture only, after you confirm; extra images and HDR brightness are not preserved. Available exports depend on your browser. No server fallback. Cancel stops the active worker; finished downloads remain available. Results are limited to 40 MiB per run.

Choose an image, select an output format and optionally a size target, then create and download the result. Compare before and after. If the target cannot be reached, review the suggested dimensions; resize only if you choose to.
