Copy the code from the previous response.
Create a new file on your computer and name it index.html.
Paste the code into that file and save it.
Double-click index.html to open it in any modern web browser (Chrome, Edge, Safari, or Firefox).
To make this tool available to the public on your domain (proainex.com):
Log in to your hosting control panel.
Go to File Manager → public_html.
Create a folder named compressor.
Upload your index.html file into that folder.
Your tool will be live at: [https://proainex.com/compressor](https://proainex.com/compressor)
Create a new repository on GitHub.
Upload the index.html file.
Go to Settings > Pages and set the source to the main branch.
GitHub will give you a free URL to share the tool.
Once the page is open, follow these steps to get the best result:
Select File: Tap the dashed upload area to select a PDF from your device.
Set Target KB:
Look at your Original Size (e.g., 750 KB).
Enter your Target Size (e.g., 100).
Note: If you set the target too low (like 5 KB for a 50-page document), the quality will be very blurry.
Rename: Enter the name you want the file to have after it downloads.
Compress: Click Start Compression.
The tool will run "Passes." It is testing different quality settings automatically to see which one gets closest to your number.
Download: Once the progress bar hits 100%, check the Final Output Size. If you are happy with it, click the green Download button.
Why it's secure: This tool uses Client-Side Processing. This means the PDF never leaves the user's phone or computer. The "Storage Device" (RAM and Browser Cache) does all the work.
The "Raster" Method: This tool turns PDF pages into images. This is the only way to guarantee a smaller size for most PDFs in a browser. Because of this, the text in the final PDF will be an image (not searchable or highlightable).
Size Limits: Large PDFs (50+ MB or 100+ pages) might slow down older mobile devices. For standard documents (1–10 pages), it is near-instant.
