Compress PDF to 1 MB

A 1 MB limit is generous enough that most everyday PDFs can meet it while keeping good quality — it is a common ceiling for email systems that block larger attachments, contact-form uploads, and content-management systems. This tool aims at 1 MB directly. It rebuilds each page as an image and then reduces the resolution and compression quality in stages, checking the size after each stage, and returns the first version that comes in under 1 MB. Because it stops at the first passing rung rather than compressing as hard as possible, a document that only slightly exceeds 1 MB will barely be touched, while one that starts much larger gets worked down further. Multi-page reports with photos or scans are the usual reason a PDF blows past 1 MB, and those normally fit after a mild pass with the text still crisp. Everything is processed in your browser — the file is never uploaded, so there is no limit on the input size and no cap on how many conversions you run.
