Frequently asked questions

Simple answers to your questions

What types of files can I compress?
You can compress common document, image, audio, and video files. Select the tool that matches your file type, upload the file, then download the reduced version.
Why should I compress a file?
Compression can make files easier to email, upload, share and store. Smaller files can also help when a website, portal or messaging platform has an upload-size limit.
Will compression change my original file?
Your original file remains on your device. The compression tool creates a separate reduced version, so you can compare the result and keep the version that fits your needs.
Can I compress files from a phone or tablet?
Yes. You can upload a supported file from a mobile browser, compress it, then save or share the resulting file from your device.
