Best for reducing image file size
Use Compress Image for photos, screenshots, and graphics that need smaller files for websites, email, forms, or storage limits.
Files are uploaded to our server, processed in memory, and automatically deleted after your download is ready. We never store, index, or share your documents.
About Compress Image
Whether you're getting product photos ready for your store, squeezing a batch of images under a form's upload limit, or just trying not to fill up your inbox - this tool does it without the usual quality hit. Upload JPG, PNG, WebP, or HEIC files (yes, iPhone photos too), pick a quality level, and optionally convert to WebP while you're at it - it's usually half the size of an equivalent JPG at the same visual quality. Up to 20 images at once, delivered in a ZIP. Files are deleted from the server the moment your download starts.
Compress Image details
Quality and compression modes
High keeps more detail, Balanced is the default for smaller files with little visible change, and Strong uses heavier lossy compression for stricter size goals.
Supported image formats
The backend reads JPG, PNG, WebP, and TIFF when the server image codecs support them. HEIC/HEIF uploads are rejected with a clear message in this environment.
Output format options
Automatic keeps a suitable format based on the upload, or you can choose JPG, PNG, or WebP. PNG is lossless, while JPG and WebP use the selected quality level.
Limits and privacy
Upload up to 20 images per batch within the site upload limit. Files are processed server-side in memory and deleted after the result is ready.
Common compression errors
Compression can fail when an image is corrupted, over 40 megapixels, too large to decode safely, or in a format unsupported by the server codecs.

Frequently asked questions
How much smaller will my images actually be?
Balanced compression typically cuts JPG photos by 50-80% with no visible difference on screen. Converting to WebP can halve the size again compared to JPG at the same quality.
Which file types can I compress?
JPG, JPEG, PNG, WebP, and HEIC (iPhone photos) all work as input. You can output as JPG, PNG, or WebP.
Can I compress a batch of images at once?
Yes - upload up to 20 images in one go and they'll all come back in a single ZIP archive.
Do you store my images after compression?
No. They're deleted the instant your download is ready - nothing is kept on the server.
