High-res scans and image-heavy presentations blow past email and portal limits fast. This compressor downsamples images and flattens the document structure, right in your browser.
Select the large PDF file you want to make smaller.
Select Low, Medium, or High compression. 'High' creates the smallest file size but reduces image quality.
Click compress. The tool will calculate your space savings and generate a smaller file instantly.
Compressing a 100MB document online means waiting for a huge upload first. Here, your device does the work, so compression happens instantly.
Financial records and contracts shouldn't be uploaded just to make them smaller. Processing happens on your machine, so your data stays local.
The algorithm targets heavy vector elements and high-res photos, converting them to optimized JPEGs so the file shrinks without visible quality loss.
Yes, to reduce file size, we must compress the images inside the PDF. The 'Low' setting preserves the most quality, while 'High' drastically reduces size at the cost of some image clarity.
Currently, our compression converts the document into highly optimized image pages. This means selectable text and hyperlinks will be flattened. If you need to preserve text, try extracting pages instead.
No. The compression happens in your own web browser. We never see your files.
Large PDFs are a struggle the moment they have to leave your computer: email attachments, job portals, government submission sites, all with 10MB or 25MB limits. This tool shrinks them by scaling down embedded images, stripping unnecessary metadata, and flattening the structure, so you get a smaller file that still looks sharp.
Online compressors want your file uploaded to their servers first, which is a real risk for financial reports, contracts, and medical records; you can't know who looks at your data or whether it's kept. Here the engine runs in your browser and the file never leaves your machine.
With no upload, compression is near-instant, even for a 150MB file. Pick a level, balanced for everyday use or maximum for strict limits, and see the space savings immediately.
