Compress PDF Online — Reduce PDF Size Free, No Upload
Shrink your PDF with a quality preset or compress to an exact target size — processed privately on your device.
100% in your browser — files never uploaded
How to compress a PDF file
Drop your PDF, pick a compression level — High Quality, Balanced or Extreme — and tap Compress. Each page is rendered on your device, re-encoded as an optimized JPEG, and rebuilt into a new PDF with the original page dimensions and orientation preserved. A live per-page progress indicator shows exactly where the job is, and the result card reports the new size and percentage saved before you download.
Compress to an exact size like 100KB or 500KB
Switch to Target file size, choose 100KB, 200KB, 500KB, 1MB or 2MB — or enter any custom KB value — and the tool automatically finds the highest quality that fits under your limit, running multiple passes so you never guess-and-retry. Ideal for government portals, exam applications and email attachment ceilings.
Which preset should you use?
Recommended is the default and fits most email and sharing situations, typically halving scanned documents. Choose Best Quality when the document will be printed or read closely, and Smallest File when maximum reduction matters more than crispness. When a portal demands a specific number, use Target size mode instead.
Private compression with no server involved
Rendering and rebuilding happen entirely in your browser — nothing is uploaded, logged or stored, which makes the tool safe for bank statements, contracts and identity documents. One trade-off to know: pages are re-rendered as images, so text in the compressed PDF is not selectable. Password-protected PDFs cannot be read; save an unprotected copy from the source application first. Files up to 50 MB are supported.
Compress a PDF to a Smaller Size — Privately, In Your Browser
Email attachment limits, upload portals with megabyte ceilings, and forms that reject anything over a few MB — a heavy PDF is a constant friction point. This compressor shrinks scanned documents, reports and image-heavy PDFs by re-rendering every page and re-encoding it as an optimized JPEG, then rebuilding a fresh PDF at the original page dimensions. The entire pipeline runs inside your browser: your document is read, rendered and rebuilt on your own device, so statements, agreements and ID scans never touch a server. There is no watermark, no signup, and files up to 50 MB are handled comfortably.
Compress a PDF to 100KB, 200KB, 500KB or Any Exact Size
Upload portals rarely ask for a compression level — they demand a number. Government application forms, bank KYC uploads, exam portals and email gateways enforce hard ceilings like 100KB, 200KB, 500KB, 1MB or 2MB, and a file even a kilobyte over is rejected. Switch to Target file size mode, pick one of the preset ceilings or type a custom KB value, and the tool searches for the highest render quality that still lands under your limit — running up to four compression passes automatically so you never have to guess-and-retry. If the target is mathematically unreachable for your page count, you still receive the smallest file the document allows, with an honest note saying so.
Or Choose a Compression Level Instead
When no portal is dictating a number, three presets cover the common cases. Best Quality re-renders pages at a generous resolution with light JPEG compression — the right pick when the PDF will be read on screen or printed and legibility matters most. Recommended is the default sweet spot for email and everyday sharing, typically cutting scanned documents by half or more while keeping text comfortably readable. Smallest File pushes resolution and quality down for maximum reduction — useful when size matters more than crispness. If the first result is still too large, run it again at a stronger preset or switch to Target size mode; page count and dimensions are preserved every time.
What Compression Changes — and What to Know Before You Download
Because pages are re-rendered as images, the output PDF is a faithful visual copy but text is no longer selectable or searchable — the same trade-off scanner apps make. This is exactly why the method works so well on scanned documents, which are already images: they compress dramatically with no practical loss. For text-born PDFs where selectable text matters, compress a copy and keep the original for editing. Already-optimized PDFs may shrink only slightly or not at all; the tool tells you honestly when that happens instead of inflating the file. Password-protected PDFs cannot be processed — save an unprotected copy first.
Frequently asked questions
Is my PDF uploaded when I compress it?
No. Every page is rendered, re-encoded and rebuilt on your own device inside the browser — the file is never transmitted to any server.
How much smaller will my PDF get?
Scanned and image-heavy PDFs typically shrink 40-80% on the Balanced preset. Already-optimized, text-only PDFs may reduce only slightly — the tool reports the honest result either way.
Will the text still be selectable after compression?
No. Pages are re-rendered as optimized images, so the output is a visual copy without selectable text. Keep your original if you need to edit or copy from it later.
Can I compress a password-protected PDF?
No — encrypted PDFs cannot be read by the in-browser engine. Open the file in its source application, save an unprotected copy, and compress that version.
What is the maximum PDF size I can compress?
Files up to 50 MB are supported, which covers most scanned documents and reports while staying inside mobile browser memory limits.
How do I compress a PDF to exactly 100KB or 200KB?
Use Target file size mode: pick 100KB or 200KB (or type a custom value) and the tool automatically searches for the highest quality that fits under that limit. If the target is unreachable for your page count, you get the smallest possible file with a clear note.
PDF ka size kam kaise kare?
Drop the PDF in, pick a compression level or switch to Target file size and type your KB limit, then download — every page is re-rendered and re-encoded on your own device.
PDF ko 100KB me kaise laye?
Use Target file size mode and choose the 100KB chip — the tool runs multiple passes to find the highest quality that fits under the limit. If 100KB is unreachable for your page count, you get the smallest possible file with an honest note saying so.
