Assignment portals, job application sites and scholarship forms often cap uploads at 1 MB, 2 MB or 5 MB, and a PDF full of photos or scans is easily bigger. Choose “Target size”, pick the limit and the tool does the rest.
It tries Light compression first, because that keeps your text selectable. If that is not small enough, it switches to Strong and searches for the highest quality that still fits under your target. Sizes use 1 MB = 1,000,000 bytes, as most upload pages count them.
Online application forms often ask for scanned documents — certificates, ID pages, letters — under a small limit such as 100 KB, 200 KB or 500 KB. Pick the matching target. A one-page scan usually fits under 200 KB; many pages may not fit under a very small limit at a readable quality.
If a target cannot be reached, the tool says so plainly and offers the smallest version it could make, with its size. Then you can remove pages you don’t need, upload pages separately, or scan at a lower resolution.
Scanned PDFs are big because every page is a photo. Light mode resizes those photos to about 150 DPI at the size they are shown — sharp on screen and in print — and saves them as efficient JPEG. That alone often makes a scanned PDF several times smaller.
Strong mode turns every page into one image at a lower resolution. That gives the smallest file, but the text can no longer be selected or searched.
Light mode changes images and nothing else. Text, links and vector graphics are left exactly as they were, so the text stays selectable and searchable — important for applicant tracking systems, similarity checkers and screen readers. If Light cannot make the file smaller, the tool tells you and offers your original instead.
Target size uses Light whenever Light is enough, and the result always tells you which method was used.
It works in the browser on Android and iPhone. Choose the PDF from your files or downloads, pick a target and download the smaller file — no app needed.
No upload, no waiting — your file is processed on your device. Large scanned PDFs take longer on a phone than on a laptop because the phone does the work.
Light keeps everything except oversized images, so the PDF looks the same and its text stays selectable. Use it first. Strong turns each page into one image: smallest file, but no selectable or searchable text. Target size chooses for you — Light if that is small enough, otherwise Strong at the highest quality that fits.
For a CV or anything read by an applicant tracking system, keep the text selectable: use Light, or a target that Light can reach. For scans and photo-heavy coursework, Strong or a target size is usually fine.
It shrinks images and, if needed, rebuilds pages as images. It does not remove pages, fonts or attachments for you, and a PDF that is mostly text is often already as small as it can be — the tool tells you when that happens.
Very small targets for long documents may not be reachable at a readable quality; the tool stops at about 72 DPI rather than make pages unreadable, and tells you the smallest size it reached. No upload, no waiting — your file is processed on your device.
Can I compress a PDF to exactly 100 KB or 200 KB?
You can set a target and the tool makes the file as good as possible while staying under it. It cannot always reach very small targets for long or detailed PDFs; then it tells you and offers the smallest version it made.
Will my text stay selectable?
Yes with Light mode, and with Target size whenever Light is enough. Strong mode turns pages into images, so the text is no longer selectable; the result always tells you which was used.
Is compressing a PDF free?
Yes. It is free with no signup and no watermark. Files can be up to 50 MB and 300 pages.
Is my PDF uploaded to a server?
No. No upload, no waiting — your file is processed on your device.
Why did my PDF not get smaller?
If a PDF is mostly text, or its images are already small, there is little to remove. The tool then says it is already well compressed and offers your original file.
How does Target size decide?
It tries Light first. If that is still above your target, it rebuilds the pages as images and searches for the highest resolution and quality that stays under the target, down to about 72 DPI. If even that is too big, you get the smallest version and a clear message.
