Bulk File Operations

Most batch file processing tools online require you to upload your files to their servers, then pay for the privilege of processing more than a handful at a time. iLovePDF, SmallPDF, and Adobe Acrobat all cap free batch processing at one to three files — not because the technology requires it, but because that is their business model. ForgePlug's Bulk File Operations tool takes a fundamentally different approach: everything happens in your browser, on your device, with no server involved at all.

Why Browser-Based Processing Is Better

When you process files in the browser, your data never leaves your device. There is no upload, no temporary server storage, and no third party that can access your documents. This matters especially for sensitive files — business contracts, medical records, personal photographs with GPS data, or financial documents. Browser-based processing eliminates the privacy risk entirely.

The trade-off is that browser-based processing is limited by your device's memory and CPU. A server has gigabytes of RAM and multiple CPU cores dedicated to the task; your browser shares resources with tabs, extensions, and the operating system. ForgePlug's tool is engineered to work within these real constraints — processing files in parallel streams, releasing memory as each file completes, and warning you honestly when a batch is large enough to risk browser instability.

How ForgePlug Handles Large Batches

Instead of processing all files simultaneously (which would crash the browser with large batches), ForgePlug uses bounded concurrency: it processes 3 files at a time in Web Workers, releasing each file's memory immediately after processing completes. Output files are streamed into a ZIP archive incrementally rather than held in memory until the end. This means you can process hundreds of files without running out of memory — as long as individual files are reasonably sized.

When a batch's total size is large enough to genuinely risk a browser crash (typically around 500 MB on desktop or 150 MB on mobile), the tool warns you proactively and suggests splitting the batch. This is an honest technical limitation, not an artificial cap — if your device can handle it, the tool lets you proceed.

PDF Operations

Compress reduces PDF file size by re-encoding and optimizing the document structure. Choose from three quality presets to balance file size against visual fidelity. Merge combines multiple PDFs into one, with drag-to-reorder control over the final page sequence. Watermark applies a text or image watermark to every page of every PDF, with configurable position, opacity, and size. Convert renders each PDF page as a JPG or PNG image, useful for sharing PDF content on platforms that do not support PDF uploads.

Image Operations

Convert changes image formats between JPG, PNG, WebP, and AVIF without uploading to a server. Resize scales images by percentage or fixed dimensions, with aspect-ratio lock as default. Strip EXIF Data removes GPS location tags and other metadata — this matters for privacy because photos taken with smartphones embed your exact GPS coordinates, and sharing those photos without stripping EXIF data shares your location. Compress reduces image file size using the Canvas API's built-in compression.
