Compress PDF

Re-save a PDF in a more compact structure without touching its images or text. Best for PDFs made on a computer; scans shrink little. Nothing leaves your browser.

About Compress PDF · বিস্তারিত

Compress PDF re-saves your PDF with its internal objects packed into compressed object streams. Images and text are not re-encoded or re-rendered, so quality and selectable text stay exactly the same, but the saving is usually small and scanned PDFs hardly shrink.

Be clear about what this tool does before you rely on it for a portal size limit. It is a lossless clean-up: it rewrites the structure of the PDF (the list of objects and cross-references) in a tighter form. It does not lower image resolution or JPEG quality, which is where most of the size in a scanned document lives.

That makes it safe for documents that must stay sharp and searchable, such as typed reports and forms. Files made by some older software can shrink noticeably; a PDF that is mostly scanned photos will stay close to its original size. The result card tells you the new size and, if it is smaller, by what percentage.

When it helps · কখন কাজে লাগে

Typed documents from older software
Reports and forms exported by older office programs often have loose internal structure that re-saving can tighten.
Quick, risk-free first try
Before re-scanning or reducing image quality, check whether a lossless re-save is already enough for an email or portal limit.
Files that must stay searchable
Legal, academic or office PDFs whose text must remain selectable can be slimmed without turning pages into images.

বাংলায়: PDF কমপ্রেস (মান না কমিয়ে)

এই টুল PDF-এর ভেতরের গঠন গুছিয়ে আবার সেভ করে, কিন্তু ছবি বা লেখার মান একটুও কমায় না। তাই লেখা আগের মতোই সিলেক্ট ও সার্চ করা যায়। তবে সাইজ সাধারণত অল্পই কমে, আর স্ক্যান করা সার্টিফিকেটের PDF প্রায় একই সাইজে থাকে, কারণ সেগুলোর বেশিরভাগ জায়গা নেয় ছবি। পোর্টালের সাইজ লিমিটে আটকে গেলে কম রেজোলিউশনে (১৫০-২০০ DPI) আবার স্ক্যান করা বেশি কাজে দেয়।

স্ক্যান করা PDF ছোট হলো না কেন?

স্ক্যান করা PDF মূলত ছবি, আর এই টুল ছবিতে হাত দেয় না। কম রেজোলিউশনে স্ক্যান করুন বা ছবি ছোট করে JPG to PDF দিয়ে আবার বানান।

কমপ্রেস করলে কি লেখা ঝাপসা হবে?

না, কোনো কিছু নতুন করে আঁকা বা কমপ্রেস করা হয় না, তাই মান একই থাকে।

Questions people ask · প্রশ্ন ও উত্তর

Why did my scanned PDF hardly get smaller?

A scanned PDF is mostly page images, and this tool does not touch images. To shrink it a lot, re-scan at a lower resolution (150-200 DPI is usually enough for documents), or make the page images smaller with an image compressor and rebuild the PDF with JPG to PDF.

Will the quality get worse?

No. Nothing is re-rendered or re-compressed, so the pages look exactly as before.

Does the text stay selectable?

Yes. The pages are not converted to pictures, so copying, searching and screen readers keep working.

The compressed file is bigger. Is that normal?

It can happen with PDFs that were already saved compactly. Simply keep your original file in that case.

Is my PDF uploaded to be compressed?

No. The file is re-saved inside your browser and never leaves your device.
