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 hard to squeeze: a quality or bitrate target, and optionally smaller dimensions if size matters more to you than detail.
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
What do I get back, and can I control the trade-off?
+
A single compressed file per input, at a quality or bitrate level you choose rather than a fixed default. If the result is not small enough, changing the dimensions or the duration will do more than pushing the quality slider further down.
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.
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.
Will Compress Image lower the quality of my images?
+
That depends on what you brought. A lossless source (PNG, BMP, TIFF) round-trips exactly; a lossy one (JPG, WebP, GIF) is already the product of one quantisation pass and only re-encodes if the operation genuinely requires it.
Can I run Compress Image on several images at once?
+
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.
What happens to metadata and transparency?
+
EXIF and the ICC colour profile are carried across wherever the target format supports them, and an alpha channel survives into any format that has one. Transparency is only flattened when the destination format has no way to represent it.
Does Compress Image cost anything?
+
No. Compress Image is free without an account and adds no watermark. Uploads are deleted from the workers shortly after the job completes.
Why does a WebM site host Compress Image?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Compress Image on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once Compress Image is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is Compress Image here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploaded video is deleted from the workers shortly after the job finishes, nothing is watched and nothing is indexed. Free accounts exist for history and batch size, not for access.
