About this tool
Gmail enforces a 25 MB total limit for email attachments. If your PDF packet exceeds 25 MB, Gmail uploads it to Google Drive as a shared link. To attach your document directly without cloud links, compress the PDF on your device first. Reducing image resolution and compressing scanned pages brings oversized files under the 25 MB ceiling while keeping text readable.
Gmail attachment size limit is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.
- No upload: on-device compression fits Gmail limits before you attach.
- Speed: processing happens instantly on your device with no upload or download delays.
- Quality: you can check your file before saving, and the original remains unchanged.
