Choose the right compression level
Start with the level that matches your upload limit, then compare the result before sharing or storing the file.
Light
Documents, images, and media where readability or detail matters most.
Use this first when you only need a moderate size reduction and want to keep the output close to the source file.
Balanced
Most email, form upload, website, and messaging jobs.
Use this when you want a smaller file while keeping a practical balance between size and output clarity.
Maximum
Files that are too large for a strict upload limit.
Use this when smaller size matters more than preserving every visual or audio detail.
When to compress instead of convert
Compress when the file format is already accepted but the size is too large for email, application forms, chat apps, or storage limits.
Open PDF compressorWhen to convert instead
Convert when a website, client, or app needs a different file type, such as JPG instead of HEIC or DOCX instead of PDF.
