About the Compress PDF
The Abzario PDF compression tool is built for heavy files, especially scanned documents that take up a lot of space. Each page of your file is re-rendered as an image and placed back into a PDF at the quality level you choose; this re-rendering is exactly what shrinks the final size noticeably. After processing, you'll see the before-and-after size so you can gauge exactly how much you saved. Because this method converts every page into an image, the text in the output file is no longer selectable or copyable; if you need editable text, use the PDF to text tool before compressing, or keep the original file. For getting scanned files down to a size suitable for email or upload to official systems, this tool alongside PDF to JPG or image to PDF can cover the whole workflow.

Worked examples
Shrinking an 8 MB scanned file
With the balanced quality setting, an 8 MB scanned file typically drops to around 2 MB, making it suitable for email attachments.
Preparing a file for an official upload portal
Many registration or job-application portals cap attachment size; heavy compression helps keep your file under that limit.
Shrinking an archive of old scanned documents
If you have a collection of old scanned documents taking up too much space, compressing them one by one frees up storage.
Frequently asked questions
Is my file uploaded to a server?
Your files never leave your device; all processing happens inside the browser.
Why isn't the text selectable after compression?
Pages are converted to images to reduce size; if you need selectable text, choose high quality or keep the original file.
Why can't I select text after compressing?
To shrink the size, each page is converted into an image and placed back into the PDF, so the text is no longer selectable or copyable even if the original file had selectable text.
Which quality level is best for office documents?
For files that just need to be readable, balanced or heavy compression is enough, but if fine details like charts or signatures matter, choose the high-quality setting.
Does compression help text-only files without images?
Compression has the biggest impact on scanned, image-heavy files; for files that were already simple text without heavy images, the size reduction is usually less noticeable.
Can I compress several files at once?
Right now the tool processes one file at a time, so you'll need to upload and compress each file separately.
