Check the output size. If it's still over 1MB, try the high compression setting to squeeze it further.
Why So Many Forms Cap at 1MB
Gmail lets you attach up to 25MB, so you might think 1MB is absurdly low. But most web upload forms — especially on government portals and job application systems — set their limit between 1MB and 2MB. These systems were built years ago and never updated.
A typical single-page text PDF is around 50-100KB. The moment you add scanned images, charts, or embedded fonts, that number jumps to 5-20MB. The biggest offender is scanned documents: a flatbed scan at 300 DPI produces roughly 3MB per page.
Our compressor resamples embedded images to a resolution that still looks sharp on screen (150 DPI) but drops the file size dramatically. Text and vector elements stay untouched, so your charts and diagrams remain crisp.
Frequently Asked Questions
Will my PDF still be readable after compressing to 1MB?
Yes. Text stays perfectly sharp since compression only targets embedded images. At medium quality, most people can't tell the difference unless they zoom in past 200%.
My PDF is 50MB. Can it really get to 1MB?
It depends on content. A 50MB file full of scanned pages can often hit 1-2MB. A 50MB file with hundreds of vector diagrams won't shrink as much since vectors are already compact.
What if 1MB isn't small enough?
Switch to high compression or try our compress to 500KB or compress to 200KB pages for more aggressive settings.
