Frequently Asked Questions

Yes, absolutely. Your files are processed directly in your browser using modern web technologies. We never upload your files to our servers, so they never leave your device. All processing happens locally on your computer or mobile device.

No, we do not store your files. Since all processing happens in your browser, your files never leave your device. We have no access to your documents, and no files are stored on our servers.

While files are processed locally in your browser, any data transmitted to our servers (such as for worker processing) is encrypted using HTTPS. However, for most operations, files never leave your browser at all.

Yes. Since we don't collect, store, or process personal data or files on our servers, we minimize data collection to the extent required for service operation. Our privacy-first approach aligns with GDPR principles.

For browser-based processing, the limit depends on your device's memory. Most modern browsers can handle files up to 100-500MB. For larger files, we recommend using desktop software.

We support PDF files for all PDF-related tools. For conversion tools, we support various formats: DOCX for Word to PDF, JPG/PNG/BMP/GIF/TIFF/SVG/WebP/HEIC for Images to PDF, and JPG for PDF to JPG.

Yes, for tools like Merge PDF and Images to PDF, you can select multiple files at once. For other operations, you'll need to process files individually.

If you're experiencing issues, please ensure you're using a modern browser with JavaScript enabled. Some older browsers may not support the web technologies we use. Try updating your browser or switching to Chrome, Firefox, or Safari.

Yes, our Protect PDF tool allows you to add password protection to your documents. You can set both an open password (required to view) and permissions password (controls what users can do).

Yes, if you know the password, our Unlock PDF tool can remove password restrictions from your document, allowing unrestricted access.

Our compression tool uses Ghostscript optimization to reduce file size while maintaining quality. For documents with images, some quality loss is possible, but we use settings that balance size reduction with readability.

Our PDF Editor allows you to add text annotations, highlights, shapes, and redactions. For extensive text editing of existing content, we recommend converting to Word format first, editing, then converting back to PDF.

Our OCR tool uses Tesseract, a powerful open-source OCR engine. Accuracy depends on image quality, font clarity, and language. For best results, use high-resolution scans with clear, legible text.

No account required. All our tools are completely free to use without signup. Just visit the tool page and start processing your files immediately.

We have no plans to charge for our tools. Our mission is to provide free, accessible PDF tools to everyone. We may add optional features in the future, but core functionality will remain free.

First, ensure your file is a valid PDF and not corrupted. Try refreshing the page and uploading again. If the issue persists, try a different browser or device. For very large files, your browser may run out of memory.

If the automatic download doesn't start, check your browser's download settings. You can also right-click the download link and select 'Save link as'. Some browsers may block automatic downloads.

Processing speed depends on your device's processing power, file size, and complexity. Large files with many pages or high-resolution images will take longer. Ensure your browser has sufficient memory available.

Error messages usually indicate issues with the file format, file corruption, or browser limitations. Try uploading a different file to see if the issue is file-specific. If problems persist, contact us with details about the error.

PDF Studios provides 14 browser-based tools covering the most common PDF tasks: merging, splitting, compressing, converting, rotating, watermarking, protecting, unlocking, signing, editing, OCR, and more. Each tool is designed to handle a specific workflow so you can complete your task without navigating complex menus.

Yes. All of our tools work in any modern mobile browser, including Chrome, Safari, Firefox, and Edge. You can select files from your device, process them, and download the results just as you would on a desktop. The interface adapts to smaller screens for easy touch navigation.

We support PDFs up to several hundred megabytes for browser-based processing, depending on your device's memory. Very large or complex files may take a little longer, but there are no artificial size limits. For extremely large batch jobs, we recommend processing files one at a time for the smoothest experience.

Absolutely. Our Merge PDF tool lets you select multiple files, arrange them in the order you want, and download a single combined document. You can reorder pages before merging and preview the result before saving it to your device.

Yes. Our Compress PDF tool reduces file size while maintaining readable quality. You can choose between light, medium, and strong compression depending on whether you prioritize quality or size. This is useful for email attachments, uploads, and archiving.

No. PDF Studios is completely free and requires no registration. You can use every tool immediately without providing an email address, name, or password. We believe in a friction-free experience, so you can focus on your work instead of managing an account.
