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.

How fast is the AVIF to JPG conversion?

Because FileConvert uses hardware-accelerated browser decoding and HTML5 Canvas, conversion typically takes less than 150 milliseconds per image.

Does this tool preserve the color profile of AVIF photos?

Yes! The browser automatically handles color space mapping, translating wide gamut colors into standard sRGB JPEG images.

Is there a limit on how many AVIF photos I can convert?

No limit! You can convert as many AVIF images as you need with zero queues, subscription walls, or watermarks.

Make Unopenable Next-Gen AVIF Files Compatible Everywhere

AV1 Image File Format (AVIF) provides extraordinary compression efficiency, and many high-traffic websites increasingly serve product photos and media in .avif format. However, standard desktop operating systems, older photo management programs, e-commerce portals, and email services still fail to open or preview AVIF files, presenting users with broken file icons or "format unsupported" errors. FileConvert leverages your browser’s native AV1 decoder and HTML5 Canvas pipeline to convert any AVIF file into a universally readable JPEG image in real time. Processing is 100% local, safe for private personal photos, and requires zero software installation.
