A practical workflow for Email Attachments
Struggling with "file too large" errors when sending emails? A browser-based compressor can help reduce routine PDF attachments without starting from an upload queue. DocuStitch is designed to make that route clear before you choose files.
Compression results depend on the PDF. Text-heavy documents usually compress differently than scanned image packets, so review the output before sending it.
Limits shown before work
File size, browser memory, and PDF structure still matter. DocuStitch surfaces practical limits before processing.
Review before sharing
Download the result to your device and inspect the output before sending it elsewhere.
Frequently asked questions about Reduce PDF Size for Email Securely (Local Optimization)
Will the images look blurry?
Compression can soften images or scans. If the file contains signatures, diagrams, or small text, compare the output against the original before sending it.
