How to Compress Image

1 Drop your images into the box above, or pick them from your device — there is nothing to install and no account to create.
2 Choose how much to compress with the setting shown for this file type: a quality level for images, a bitrate for audio, or a target size or quality level for video.
3 Start the job and let the workers re-pack the file; your original is never modified in place.
4 Compare the new size against the original, then download the compressed Image file.

Compress Image FAQ

Does the format of my file change how much I can save?
+
Very much so. this format is read and written by the same streaming pipeline as everything else we support. That determines both the headroom available and whether the saving costs you anything in fidelity.
Yes — the pipeline reads the real format from the file header rather than the extension, so a mislabelled upload still works. It is worth knowing before you overwrite an original you might need again.
Compressing the same file repeatedly. Each pass on a lossy format is a fresh generation of loss and the savings shrink while the damage accumulates. Go from the original to your target in one step, and keep the original.
Concretely, the right strategy is chosen per file — re-quantisation for a lossy source, stronger lossless packing for a lossless one — so a mixed batch does not get one blunt setting applied to everything. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
Yes, and mixing formats in the batch is fine — settings are applied per file with the right decoder for each. Free accounts run one file at a time; a pass removes that.
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Compress Image shares the upload, the caps and the account with the conversions for that reason.
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
