Are my files ever uploaded to any server or cloud?

Never. FileConvert is 100% client-side. When you drop or select a file, your browser processes the bytes directly in device memory using HTML5 Canvas and pdf-lib. Zero bytes of your sensitive images or documents ever leave your phone or computer. You can verify this by turning off your internet connection—all tools will continue working normally.

Which image formats are supported for compression & conversion?

FileConvert supports all common formats including PNG, JPG/JPEG, WebP, GIF, SVG, and BMP. You can cross-convert between WebP, PNG, and JPG while choosing your exact target quality or specifying an exact target file size in kilobytes (KB).

How does client-side PDF merging work in the browser?

We use pdf-lib, an open-source binary PDF manipulation library running in browser JavaScript. It reads the raw byte streams of your PDF files, parses the page dictionary structures, copies page streams into a consolidated document, and serializes the new PDF binary directly to your local downloads without requiring backend server rendering.

Is there any file size limit?

Unlike traditional online converters that impose 5MB or 10MB limits, FileConvert has zero arbitrary server limits. The only constraint is your device’s available browser memory (RAM). Most modern smartphones and laptops easily process files up to 200MB+ in seconds.

How is performance and low INP (Interaction to Next Paint) maintained?

Heavy operations like image downsampling, quantization, and PDF byte stream packing are scheduled with asynchronous microtasks. This yields control back to the browser main thread between computational steps, ensuring the UI stays fluid at 60fps with minimal input latency during high-resolution processing.

What happens to transparent backgrounds in WebP images?

Because JPEG does not support alpha transparency, transparent areas are automatically filled with clean solid white (#FFFFFF), preventing black box artifacts.

Are my WebP photos uploaded to a remote server?

No! All rendering and conversion occur directly inside your device’s browser memory via the HTML5 Canvas API. Files are never transmitted over the internet.

Can I batch convert dozens of WebP files at once?

Yes! You can drop or select multiple WebP images simultaneously and download all converted JPGs individually or as a single combined ZIP archive.

Universal Compatibility for Legacy Software, Portals & Print

While Google WebP offers superior compression for modern web pages, many traditional image viewers, government submission portals, school portals, older email clients, and professional desktop design suites still refuse to accept .webp files. Users who download images from Chrome or mobile browsers frequently find themselves unable to attach or print WebP files. FileConvert decodes your WebP images directly in local browser memory and exports them into pristine, high-density JPEG files with selectable quality levels. Because conversion is performed 100% on your device, you enjoy instant batch processing with zero wait times and complete confidentiality.
