Frequently Asked Questions
Are my PDF files uploaded to your servers?
No. All PDF processing on ToolGrid happens entirely in your browser using WebAssembly and JavaScript. Your files never leave your device and are never sent to any server.
Is there a file size limit for PDF tools?
There is no enforced file size limit. Performance depends on your device's memory and processing power. Most modern computers handle PDFs up to several hundred megabytes without issues.
Do the tools add watermarks to my PDFs?
Never. ToolGrid PDF tools produce clean output with no watermarks, branding, or modifications beyond what you explicitly request.
Can I use these tools on mobile?
Yes. All PDF tools work on any modern browser including Chrome, Safari, Firefox, and Edge on both desktop and mobile devices.
Do I need to create an account?
No account is needed. All tools are immediately accessible without registration, login, or providing any personal information.
What PDF versions are supported?
ToolGrid PDF tools support PDF 1.4 and above, which covers the vast majority of PDFs created in the last 15 years.
Can I process password-protected PDFs?
Use the PDF Password tool to remove the password first, then process the file with any other tool. Password removal requires you to know the current password.
Is my data safe with browser-based PDF tools?
Browser-based processing is actually more secure than server-based tools because your file content is never transmitted over a network. The file is processed in memory on your own device and discarded when you close the tab.
How to merge PDF files online
To merge PDF files without installing software, open the PDF Merge tool, drag and drop your files into the upload area, arrange them in the order you want, and click Merge. The combined PDF downloads to your device instantly — no account required.
How to compress a PDF without losing quality
Open the PDF Compress tool and upload your file. The tool removes redundant data and optimizes embedded resources. For most PDFs, you can reduce file size by 40–70% with no visible quality loss. If you need aggressive compression, choose the "Maximum" setting.
How to split a PDF into separate pages
The PDF Split tool lets you extract individual pages or page ranges from any PDF. Specify the pages you want (for example "1, 3-5, 8") and download each section as a separate PDF file.
