Choose
Your browser reads PDFs you choose. They are not submitted to MiluLand.
Your PDFs stay on your device.
From loading and previewing to reorganizing and downloading, PDF contents stay inside this browser tab. Here is what happens at each step.
Preview
Page thumbnails are generated in local memory and shown only in this tab.
Organize
Merge, extract, rotate, delete, and reverse operations run in your browser.
Download
A new PDF is created only after your action and saved by your browser where you choose.
PDFs, thumbnails, and memory
Heye PDF uses JavaScript, PDF parsing, and Canvas in your browser. Original PDFs, page text, thumbnails, and newly generated PDFs are not uploaded to MiluLand servers. Refreshing or closing the tab clears current files and previews from page memory; we cannot view or recover them.
Where preview code comes from
Page previews load the open-source PDF.js worker code from the jsDelivr CDN. That request fetches program code and does not include your PDF contents; document data is then processed locally. The CDN may receive ordinary access data such as IP address, time, and browser information.
Files you choose to export
Merge, extract, and organize actions download new PDFs. ‘Download plan’ creates a plain-text TXT containing file names, page counts, sizes, and page ranges—not PDF page contents. None of these files are automatically sent back to us.
Ads and local storage
The site uses Google AdSense. Depending on your region and consent choices, Google may use cookies or local storage for ad delivery and measurement.
Preferences and favorites
Language, theme, and high-contrast choices are stored in your browser. These display preferences and up to 16 favorite tool IDs also use .miluland.com domain cookies so same-domain pages stay consistent. Favorites never contain inputs, files, or results, can be cleared from the MiluLand tool directory, and are not intentionally uploaded.

Optional analytics
This site loads Google Analytics only after your explicit permission to measure visits to tool and information pages. File names, file contents, tool inputs, search terms, QR payloads, URL parameters, and results are excluded. Google's enhanced measurement is off.
Your choice is saved in a .miluland.com cookie for 180 days and shared by MiluLand pages with analytics enabled. Use ‘Analytics choices’ at the bottom of the page to decline or withdraw permission; withdrawal disables measurement and clears accessible GA cookies. Browser GPC and Do Not Track keep analytics off. Advertising has separate Google consent settings.
