Secure your PDF with strong password protection and encryption.
Reduce file size without losing quality.
Need your PDF to be exactly 200KB, 500KB, or 2MB? Our tool lets you specify the exact file size you want. Perfect for strict upload limits, email quotas, and professional requirements. No sign-up, no software – just upload, set your target, and download.
Did you know? Many online platforms enforce strict file size limits – and they vary. With our exact‑size compression, you can tailor your PDF to fit any requirement, whether it's 100KB for a job portal or 2MB for an email attachment.
Different platforms and use cases demand different file sizes. Having control over the exact output size saves you from trial‑and‑error.
Here are common scenarios where exact‑size compression is essential:
Job portals, government forms, and academic submission systems often have fixed limits like 200KB or 1MB. You need to hit that exact number.
Some email servers reject attachments over 500KB or 1MB. Compressing to the exact limit ensures delivery without reducing quality more than necessary.
When sending documents to clients or partners, you may want a predictable file size for easier handling and storage.
For batch archiving, keeping files under a specific size helps manage storage quotas efficiently.
Different content types respond differently to compression. Here’s a guide to what’s realistic for common target sizes:
Our tool will adjust compression levels to meet your target as closely as possible, but extreme targets may result in lower visual quality.
Achieving a precise file size requires an intelligent, iterative process. Here’s what our tool does:
The result is a PDF that closely matches your desired file size, balancing quality and file size automatically.
Follow these simple steps to get your PDF to the exact size you need:
DonePDF Compress PDF and upload your file.
Enter your desired target size (e.g., 500, 1200) and choose the unit (KB or MB).
Click "Compress to Exact Size" – the tool will process and adjust until the target is reached.
Download your perfectly sized PDF.
If the target is too small for the content, the tool will compress as much as possible and notify you of the minimum achievable size.
Our algorithm automatically selects the right compression intensity based on your target. Here’s how different levels relate to size:
The tool automatically chooses the right intensity to meet your target. For very small targets, we recommend using our Hyper Compress tool for additional reduction.
Alternatives you might consider:
Our tool gives you complete control: set any size, and we do the work to get as close as possible – automatically and accurately.
Pro Tip: For scanned documents, use OCR to extract text first – then compress. Text-based PDFs give you much finer control over the final size.
Set any file size you need – no more guessing.
No manual trial‑and‑error – the tool adjusts automatically.
Meet any platform’s file size limit effortlessly.
Automatically balances quality and size to hit your target.
🚀 Need an extremely small size? Try Hyper Compress
If your target is below 100KB or you need maximum reduction, our Hyper Compress tool applies aggressive JPEG compression and grayscale conversion to get you there.
You upload your PDF and enter your desired target size (e.g., 200 KB, 1.5 MB). Our tool then applies compression iteratively – adjusting quality, DPI, and image compression – until the output file matches your target as closely as possible.
Yes. You simply type "500" in the size field and select KB. Our tool will attempt to get as close to 500KB as possible, using a combination of compression techniques.
In most cases, we can get within 5‑10% of your target. However, if your original file is extremely small (e.g., 50KB) and you request 10MB, we cannot inflate the size – compression only reduces file size.
We use a smart algorithm that repeatedly applies compression (image downsampling, JPEG quality reduction, metadata stripping, font subsetting) with varying intensity until the target size is reached.
Absolutely. We use TLS encryption and auto-delete all files within 2 hours. Your privacy is protected.
Our tool works with any PDF file – text, images, or scanned. The algorithm adapts to the content to meet your target.
Processing usually takes 30‑60 seconds, as the tool may need to run multiple compression passes to fine‑tune the size.
Upload your PDF, set your target, and download a perfectly sized file – fast, secure, and ready for any platform.
Reaching a strict file size target requires a combination of techniques: aggressive image downsampling, metadata removal, font subsetting, and efficient stream compression. Our tool automates these processes to help you achieve your target quickly.
Hitting an exact file size can be tricky. Our tool allows you to adjust compression levels and preview the resulting size before downloading. Use "Maximum" for the smallest size, then incrementally adjust to reach your exact target.
If you cannot reach your target without unacceptable quality loss, consider splitting the PDF into multiple files or using our Hyper Compress tool for extreme reduction. For text‑only documents, quality loss is minimal even at maximum compression.
