1MB is the everyday limit: job portals, college applications, many online forms and plenty of email systems ask for files under 1MB. Most documents get there with gentle compression. This page opens the compressor aimed at 1MB, has no cap on how large the original can be, and keeps the file on your device.
To compress a PDF to 1MB, set the target to 1MB rather than picking a level. On ihatepdf this page opens already set to under 1MB: add your PDF, even a large one, and press Compress. It tries up to six progressively stronger settings and keeps the first result under 1MB, shows the exact size, and processes the file in your browser without uploading it.
Job portals, university application systems, many government e-services and older email systems cap attachments around 1MB. It is a round number that keeps storage and upload times low. Text documents are almost always under it already; scans, photographed pages and designed brochures are what push files over.
A big PDF is usually big for one reason: high-resolution images. The first step of the ladder brings images to 150 DPI, which alone can cut a 20MB scan by more than 80%. If the file has hundreds of pages, 1MB may not be reachable at readable quality, and the tool will tell you rather than produce a blur. Split PDF by size can then cut it into parts under 1MB each.
After compressing, the tool re-opens the output and compares its page count and extracted text with the original. If anything does not match, it hands you the original instead. You never download a file that looks fine in the list but is missing a page.
Open this page, add your PDF and press Compress. It is already set to 1MB. There is no daily limit, no sign-up and no watermark, and it shows you the final size before you download.
Often, yes, if the size comes from scanned or photographed pages. A 30-page colour scan has a lot of room to shrink. Whether it reaches 1MB depends on how many pages it has; if not, the result is labelled "smallest possible" and the explanation says what is taking the space.
Yes. Applicant-tracking systems read the text layer, which compression does not touch. Only the photo and graphics are re-encoded.
No fixed limit. The file is processed in your browser, so the ceiling is your device's memory; files up to about 150MB work on a typical desktop browser.
No. Everything runs locally in your browser and the file never leaves your device.
