Free Image Compressor Online Compress photos without uploading them.

Shrink image files for websites, email, forms, ecommerce, and social platforms. Use automatic compression for quick results or advanced target-size mode when you need a file under a specific KB or MB limit.

Choose the right image compression mode

Our image compressor matches the job you assign: smaller website images, strict upload limits, or clean photo sharing.

Automatic compression:
Best for everyday images when you want smaller files quickly while keeping the picture visually close to the original.
Target-size compression:
Use this feature when a portal says the image must be under 100KB, 200KB, 1MB, or another exact file-size limit.
Format-aware compression:
JPG compressor is usually best for regular photos, PNG compressor for transparency, WEBP compressor for modern websites, and TIFF compressor for workflows that begin with high-quality source files.
Resize plus compress:
When a file is still too large, lowering dimensions with the image resizer can preserve quality better than extreme compression alone.

Image Compressor FAQ

Start with automatic compression. If the file is still too large, reduce dimensions slightly before using stronger compression. This usually keeps the image cleaner than forcing quality too low.

JPG is usually best for photos, PNG is best for transparency and graphics, and WebP often gives the smallest files for websites when supported.

Yes. Use Advanced mode to choose a target in KB or MB, or use preset pages such as 100KB, 200KB, 1MB, and 2MB.

Not always. Compression can reduce file size while keeping dimensions. If you also need a different width and height, use the resize controls before export.

Yes. Add several files, process them together, and download the compressed results as individual files or a ZIP.

No. Compression happens in the browser, so private images remain on your device.

Large PNG photos or transparent graphics can remain heavy. If transparency is not required, converting to JPG or WebP can reduce the file size much more.
