Frequently Asked Questions
Yes, for a single-page document, ID card scan, or a digital signature, 20KB is perfectly sufficient and will remain readable on a screen. However, if you attempt to squeeze a multi-page, image-heavy document into 20KB, the visual quality will be noticeably reduced to meet the strict size requirement.
Government and academic portals reject files that are exactly on the maximum limit. To prevent application errors, our tool is specifically calibrated to land just under the target size. Additionally, PDFs with fully embedded fonts or complex vector graphics have a "structural floor," meaning they can only be compressed so much without breaking the file.
Absolutely. Your privacy is our top priority. We use strict transport-level security (HTTPS) for uploads, process your file in an isolated sandbox environment, and permanently delete all original and compressed files from our servers automatically after 15 minutes.
Yes! While the default is 20KB, you have full control. Once you upload your file, simply edit the "Target Compression Size" box to any custom limit (in KB or MB) required by your specific application portal before hitting compress.
No, we never add watermarks, branding, or logos to your documents. The PDF you download is exactly the same as the one you uploaded, just optimized for a smaller file size.
You can upload and compress PDF files up to 50MB in size. If your file is larger than this, we recommend splitting the PDF into separate pages first before compressing.
Yes, our tool is fully responsive and works perfectly on iOS and Android devices. You can select a PDF directly from your phone's files or iCloud/Google Drive and compress it on the go without installing any apps.
If you have a JPG or PNG image of your signature, you must first convert it to a PDF format. Once it is a PDF file, upload it to this tool, set your target size to 20KB, and we will optimize it to fit your exam or job portal requirements.
