Privacy guaranteed
Many tools process images directly in your browser. When server processing is required, transfers are protected and limited to what the tool needs.
Compress JPG online
For JPEG images, the quality slider controls the balance between file size and visual detail. Lower values usually produce smaller files but can make compression artefacts more noticeable. Compare the exported image with the original before keeping the result. For compression, judge the useful result rather than the preview alone. Also discover our tool to convert an image.
PNG and WebP compression
Optimize your PNG images with transparency or convert to WebP for even smaller files. Use WebP or keep PNG. Yes, but note that converting to JPEG will remove transparency. When working on compression, check the change where detail actually matters. This catches outliers without turning every file into a separate job.
How many images can I compress at once
You can add up to 50 images per batch, with a maximum size of 10 MB for each file. Compression runs directly in your browser. The number of processing actions available also depends on your daily allowance, and the interface warns you when that allowance is reached. Before you accept the compression result, compare it with the source file.
Image processing
Many tools process images directly in your browser. When server processing is required, transfers are protected and limited to what the tool needs. Source files can differ in dimensions, framing, contrast and fine detail, so one setting may not suit every exception. Start with the image's final use in mind.
Reduce size for email
Send your images by email without exceeding size limits. Our tool reduces weight while keeping sufficient quality for on-screen viewing. After compression, open the exported file and check it in its final context. For a group of images, test one representative file before applying the same operation to the whole batch.
