100% Browser-Native: Your documents are optimized directly on your device. We never copy, upload, or process your files on our servers.
Uploading certificates, marks sheets, or identity proofs to portals like EPFO (Employees' Provident Fund Organisation), state education boards, and recruitment portals requires PDF attachments to be under 100KB. This limit can be difficult to hit because scanned files are often larger than 1MB. Using ToolWala's client-side PDF compressor, you can shrink your documents under 100KB safely and quickly.
How to Compress PDF to 100KB
1. Click the **Go to PDF Compressor** button above to open the main optimizer tool.
2. Drag and drop your PDF document or browse your files locally.
3. Select the target compression parameters to automatically lower resolutions and strip unused font subsets.
4. Download the resulting file under 100KB instantly.
Why 100KB Upload Caps Exist
Portals enforce strict file size caps to handle millions of uploads efficiently. If every applicant uploaded a 5MB certificate scan, it would slow down servers and consume massive storage. By enforcing a 100KB limit, portals ensure fast uploads, but candidates must optimize files. Our resizer resolves this problem locally on your device.
Keeping Text Legible at 100KB
A major challenge when compressing under 100KB is keeping text legible. Our engine uses smart compression to scale down background colors and graphics while keeping text clean, ensuring that your application is not rejected due to unreadable details.
Security and Privacy Assurance
Since certificates contain personal details (names, dates of birth, registration numbers), uploading them to online converters poses privacy risks. Our PDF compressor processes files entirely in your browser cache, ensuring your data never leaves your computer.
