1Drop your images into the box above, or pick them from your device — there is nothing to install and no account to create.
2Choose 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.
3Start the job and let the workers re-pack the file; your original is never modified in place.
4Compare 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.
Is there anything specific to Image I should know before compressing?
+
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.
How does Compress Image actually make the file smaller?
+
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.
How much smaller will my file get?
+
That is decided by the content, not by the tool. Photographic detail and film grain resist compression; flat colour, text and silence collapse. A realistic expectation is a large reduction on anything with big uniform regions and a modest one on a busy photograph or a high-motion clip.
Which image formats does Compress Image accept?
+
All of the common ones — JPG, JPEG, PNG, WebP, GIF, BMP, TIFF, SVG, ICO, PSD, JFIF and HEIC. You can mix formats freely in one batch; each file is identified from its header and routed to the right decoder.
Is there a file size limit on Compress Image?
+
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.
Why would a modern-format site run Compress Image?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. Compress Image is on the same upload and the same account so those questions get answered in one place.
Once Compress Image has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
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.
