Compress PDF to 1MB
1MB is the classic email attachment and portal cap. This tool takes your PDF under the limit with staged image compression — text stays perfectly sharp and selectable.

Will a 1MB target hurt readability?
For typical business documents, no — text is untouched and image quality is reduced only as far as needed to hit the target.
What if my file is still over 1MB?
Extremely photo-dense documents have a compression floor. You always get the smallest achievable result; splitting the document or compressing to 2MB are practical fallbacks.
Is the 1MB compressor free?
The first conversion is free with no account. Regular use starts at $5/month.
