MinoPDFCompress PDF to Target Size
Shrink a PDF to fit under a target like 100 KB, 200 KB, 500 KB, or 1 MB. The tool searches for the smallest settings that reach your goal, then stops. If it cannot, it shows the smallest readable result and says so. Private, runs locally.

Full method & limitsKey Features
Pick a Target Size
Choose 100 KB, 200 KB, 500 KB, or 1 MB. The tool aims for that ceiling instead of a fixed quality.
Searches for the Smallest Fit
It tries settings from fine to coarse and stops as soon as the file fits under your target, so quality stays as high as possible.
Honest Result
When the goal cannot be met, it returns the smallest readable result and tells you, instead of shipping a file that is still too big.
Keeps Text Selectable When Possible
On text-based PDFs the search uses structure optimization, so words stay selectable unless pages must be re-encoded.
Scans and Photos
Image-heavy and scanned PDFs are re-encoded page by page to reach the target when structure tuning alone is not enough.
Private and Local
Compression runs entirely in your browser. Your PDF never leaves the device and is not sent to any server.
How to Use
Add your PDF
Drag and drop or select a single PDF, such as a document that must be emailed as an attachment under a size limit.
Choose a target size
Pick 100 KB, 200 KB, 500 KB, or 1 MB depending on where you need to upload or send the file.
Review and download
Run the search, see whether the target was reached, then download the result or pick a lower target if needed.
Compress PDF to Target Size Example
A 5 MB report is searched down to a 480 KB file that fits under the 500 KB target while staying readable.
report.pdf (5 MB)
A report that must be uploaded to a portal with a 500 KB attachment limit.
report-compressed.pdf (480 KB)
The tool tried several settings and stopped once the file was under 500 KB, showing Target 500 KB / Reached.

How to Compress a PDF to a Specific Size
Use this tool to shrink a PDF until it fits under a target such as 100 KB, 200 KB, 500 KB, or 1 MB. Compression runs locally in your browser, so your file never leaves the device.
Quick Answer
Upload a PDF, pick a target size, run the search, check whether the target was reached, then download the result. If it did not fit, try a larger target or the Maximum level on the plain Compress PDF tool.
How the Search Works
The tool first tries lossless structure optimization: rewriting the file, removing redundant metadata, and compacting the internal structure. If that is already under your target, it stops there and text stays fully selectable. If not, it re-encodes pages as images, trying settings from fine to coarse — higher resolution and higher JPEG quality first, then progressively smaller — and stops the moment the file fits under the target. This way quality stays as high as the goal allows.
100 KB, 200 KB, 500 KB, or 1 MB
These four targets cover the most common limits: email attachments, web forms, and upload portals. A 1 MB target is reasonable for a multi-page report; 100 KB or 200 KB is tight and usually means pages become images, so text is no longer selectable.
When the Target Cannot Be Met
Not every PDF can reach a tiny target. A scan that is already compressed, or a document with many detailed images, may have little room left. When the search exhausts its settings without fitting under the target, the tool returns the smallest readable result and tells you the target was not reached. That honesty matters more than a fake success: you can then decide whether a larger target is acceptable.
Check the Preview Before Sharing
If pages were re-encoded as images, open the preview and read a page or two. Make sure the text is still clear enough and that you do not need selectable text, links, or forms. For text-based PDFs, prefer the smallest target that still keeps the document usable.
