Compress reports, resumes, scanned documents, forms, invoices, presentations, and other PDFs. Upload your file, choose a compression level, process the document, and download the smaller PDF without installing extra software.
Upload the PDF you want to compress
Click Select PDF file and choose a document from your device, or drag and drop it into the upload area. You can compress reports, resumes, presentations, scanned documents, invoices, forms, manuals, and other PDF files up to the supported upload limit.
Choose the right compression level
Select the compression option that matches your goal. Recommended compression is suitable for most documents, while stronger compression focuses on reducing file size further. A lighter option can be useful when image quality and fine details are more important.
Reduce PDF size without changing the file format
The document remains a PDF after processing. EDITHUBS optimizes supported images, fonts, page resources, and unnecessary internal data while keeping the file compatible with common PDF readers.
Make PDFs easier to email and share
Large PDF attachments can be difficult to send through email, messaging apps, learning platforms, and online forms. Compressing the file makes it easier to upload, share, store, and download on slower connections.
Compress scanned and image-heavy PDFs
Scanned documents and image-based PDFs often use more storage than text-based files. Compression can reduce the size of embedded page images while keeping the document readable for everyday viewing and printing.
Keep text and page structure readable
The compression process is designed to preserve page order, text, links, forms, and common document structure. Results can vary depending on how the original PDF was created and how much optimization has already been applied.
Compare the original and compressed size
After processing, the result screen shows the original file size, compressed file size, and the amount of storage saved. This makes it easy to see how much the document was reduced before downloading it.
Review the compressed document
Open the downloaded PDF and check important pages, images, charts, small text, and form fields. If the result is too compressed, process the original file again with a lighter setting.
Download and save the smaller PDF
When compression is complete, download the optimized PDF to your device. You can rename it, send it by email, upload it to a website, or keep it as a smaller copy while preserving the original document.
