Privacy details

Image compressor processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using the image compressor

Lower quality discards more image detail, which can reduce file size. The preview is rendered locally and the displayed byte count is measured from the encoded file. A solid background replaces transparency for JPEG.

A worked example

The default exports the 640 × 360 example as JPEG at a quality setting of 80%. The byte count comes from the resulting file, not a promised reduction.

Before you use the result

PNG, JPEG and WebP inputs are decoded by your browser. Animated files use their first frame. Color profiles can affect displayed colors; exports are rendered pixels, not the original metadata.
