FAQ
Can I compress a 50MB PDF to 1MB?▾
It depends on the content. A 50MB PDF full of high-resolution photos may compress to 2-5MB with these settings. A 50MB document with mostly text and simple graphics can easily reach 1MB or less. For maximum compression of very large files, try the Maximum Compression preset.
Does compression affect PDF forms?▾
No. Interactive form fields, fillable text boxes, checkboxes, and dropdown menus remain fully functional after compression. Only embedded images are optimized to reduce file size.
What email services have a 1MB limit?▾
While most modern email services allow 10-25MB attachments, some corporate email systems, older webmail providers, and certain online submission forms may impose smaller limits. Compressing to 1MB ensures your PDF works virtually everywhere.
