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.

Privacy & Security

Privacy Policy

Last Updated: October 19, 2026 • Effective Date: October 19, 2026

100% Client-Side Privacy Guarantee

At FileConvert, we believe your files belong exclusively to you. Unlike conventional online converters that upload your photos, financial statements, and resumes to remote cloud servers, FileConvert executes 100% of its file conversion and compression routines locally inside your web browser.

1. Information We Do Not Collect

We do not collect, view, store, transmit, or monetize any user-uploaded files. Whether you are compressing a confidential tax PDF, converting an iPhone HEIC picture, or optimizing a digital signature, your documents never touch an external backend API or cloud bucket.

2. Technical Execution & Local Storage

Our tools utilize standard web technologies including HTML5 Canvas, WebAssembly (Wasm), Web Workers, and local JavaScript libraries (such as pdf-lib, pdfjs-dist, and heic2any). Files exist only in volatile browser memory while the tab is active and are automatically garbage-collected when you reload or close the tab.

3. Analytics & Network Logs

When you load the FileConvert website, hosting edge servers (such as Vercel or Cloudflare) automatically receive standard technical metadata—including your IP address, browser type, operating system, referring URL, and page request timestamps. This data is utilized strictly for DDoS mitigation, traffic routing, and CDN caching optimization.

4. Cookies & Third-Party Advertising Disclosures

FileConvert does not set invasive tracking cookies for its core tools. To support ongoing free access and server infrastructure, we may partner with third-party vendors, including Google, to serve relevant advertisements.

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our site and/or other sites on the Internet.
Users may opt out of personalized advertising by visiting Google Ads Settings or by visiting www.aboutads.info.

5. Children's Privacy

FileConvert does not knowingly collect or solicit personal information from children under the age of 13. Because our service does not require user registration or file uploads, no personal child data is ever stored.

6. Changes to this Policy

We reserve the right to update this Privacy Policy to reflect technical or legal requirements. Any modifications will be posted here with an updated effective date.
