    How it works

    How to get a PDF under 1 MB

    1. Drop your PDF

      Custom size is already set to 1 MB on this page. Change the number if your form allows a different limit.

    2. Check the estimate

      After a few seconds you see the smallest size this file can reach. If that is above 1 MB, the tool says so and shows how many parts it would take.

    3. Choose one file or parts

      Run it as one file when it fits. When it doesn’t, take the Smallest version or split it into numbered parts that each stay under 1 MB.

    4. Check and download

      Zoom in on the preview to check digits and stamps, then download the file, or all parts in one ZIP.

    Why it’s different

    Hitting a hard limit, honestly

    Estimate first

    Sizes are estimated from sample pages of your own file, not from a generic table, so you know where you stand before anything runs.

    Fits, or tells you

    When one file can’t get under 1 MB with readable text, the tool says so up front instead of handing you an unreadable file.

    No charge for a miss

    If the target can’t be reached you pay nothing, and you can still download the smallest version within an hour or switch to splitting.

    Good to know

    Can every PDF be compressed to under 1 MB?

    No, and it helps to know why. A one-page letter or a short text PDF usually gets there easily. A long color scan, a photo-heavy brochure or a 100-page document may hold more detail than 1 MB can carry while staying readable.

    The tool works this out per file. If 1 MB is within reach, it aims for one file. If it is close, it tries and charges nothing if it misses. If it is far off, it tells you the smallest realistic size and how many parts you would need.

    Why do so many forms set a 1 MB limit?

    Job portals, school enrolment systems and online public services often cap each attachment at 1 or 2 MB to keep storage and review queues manageable. The cap applies per file, so a document that is even slightly over is rejected outright.

    Always use the limit printed next to the upload button rather than a number you remember from another site. Limits differ between services and can change. For 5 MB limits, see how to compress a PDF under 5 MB.

    Split or squeeze: which is better?

    If the form accepts several files, splitting usually wins. Each part keeps more detail, and the reviewer can read every page. Squeezing a 40-page scan into a single 1 MB file can leave small print and stamps hard to read, which may get an application sent back.

    If the form accepts only one file, remove the pages it doesn’t need first with Organize PDF, then compress what remains. Fewer pages leave more room for each one.

    What if the file is only just over 1 MB?

    Try the Smallest level and check the preview: for a file that is close, it is often enough. Blank pages, duplicate pages and cover sheets add weight without adding information, so removing them closes the gap too. If the result still sits above the limit, you pay nothing and can split instead.

    FAQ

    Frequently asked questions

    What if my file can’t get under 1 MB?

    Let the tool split it. Each part stays under the limit, and the parts are numbered so the order is obvious. If the form only takes one file, take the Smallest version and check it, or remove pages you don’t need first.

    Am I charged if the 1 MB target is missed?

    No. A custom size that can’t be reached is not charged. You can still download the smallest version that was achieved within an hour, or switch to splitting the file into parts that fit.

    Is 1 MB the same as 1,000 KB?

    Not always. Some sites count 1 MB as 1,000 KB and others as 1,024 KB. The difference is small, but it matters when a form is strict. Aim slightly below the limit, for example 0.95 MB, so the file fits either way.

    Can I choose another size, like 2 MB or 500 KB?

    Yes. Custom size is only preset to 1 MB on this page. Type the limit your form asks for, such as 2, or 0.5 for 500 KB, and the estimate updates for your file.

    Is it free? What are the limits?

    Yes. On the free tier each file can be up to 100 MB and 500 pages. You get 5 free credits every day (enough for one Recommended compression of up to 20 pages). Merge, split, organize and image tools are free for files up to 20 MB / 100 pages. Up to 3 files at a time (10 with credits, 20 with Pro). Credits raise the limit to 200 MB and 2000 pages per file.

    How long do you keep my files?

    Files are deleted automatically 24 hours after processing on the free tier, 3 days with credits and 7 days with Pro. You can press “Delete now” at any time, or keep a file 30 days for 2 credits. Only you can download files from your results page, unless you create a share link yourself (up to 24 hours or until the file is deleted, and you can revoke it). Files are never sent by email.
