Select from our dedicated browser utilities. Each tool is optimized for speed, preserving original document formatting and image crispness without external software.
PDF & Document Converters
Convert PDF to Word and Word to PDF instantly. Clean, high-quality layout preservation without file uploads.
Image & Compression Tools
Resize web images and compress heavy files in seconds. Quick browser-side optimization for remote workers.
** If your compressed image is still larger than expected, try unchecking the "Keep aspect ratio" box and entering both a custom width and height manually. This gives you full control over the final file size. Leaving width and height blank compresses the image without resizing it, which may limit how small the file gets.
Two of the most common everyday digital tasks — converting a Word document to PDF and compressing large image files — are now completely free and instant on CalcTool. No software to install, no files uploaded to any server, no signup required.
Word to PDF Converter
Sending a Word document as a .docx file is risky — the formatting can look completely different on the recipient's device depending on their version of Microsoft Word or whether they use Google Docs. PDF solves this permanently. A PDF looks identical on every device, every screen size and every operating system.
Our Word to PDF Converter processes your document entirely inside your browser. Your file never leaves your device — making it completely private and safe for sensitive documents like CVs, contracts, salary slips, legal papers and business reports. Simply upload your .docx file, choose your page size, orientation, font size and margins — and download a clean PDF in seconds.
The tool also works in reverse — the PDF to Text extractor pulls all readable text out of any PDF file and lets you download it as a .txt file or copy it directly to your clipboard. Useful for extracting content from bank statements, reports and downloaded documents.
Image Compressor and Resizer
Photos taken on modern smartphones are typically 3 MB to 8 MB each. Sending these on WhatsApp, attaching them to emails or uploading them to websites causes slow loading and storage problems. Our Image Compressor reduces file size by up to 90% while keeping images sharp and clear.
Supports JPG, PNG, WebP and GIF formats. You can compress a single image or process multiple images at once in batch mode. Set a custom width and height to resize along with compressing — or uncheck Keep Aspect Ratio for maximum size reduction with full control over dimensions.
All processing happens inside your browser. Your images are never uploaded to any external server, making this the safest image compression tool available online.
Absolute browser privacy
By processing files locally in your browser, your sensitive data never uploads to a remote server. Your documents remain entirely yours, protected by local-only execution.
We never store, track, or inspect your files. Once you close the tab, all processed data is permanently cleared from your device memory.
