Security & Vulnerability Reports

Reports of potential client-side memory safety risks, dependency CVEs, or CSP bypasses are prioritized with an immediate 12-hour engineering triage SLA to ensure zero-risk user execution.

Coordinated Vulnerability Disclosure Policy

In accordance with internet safety best practices and RFC 9116 principles, security researchers are invited to submit findings directly to info@convertheictopdf.com with the subject line [SECURITY AUDIT]. Please provide detailed reproduction steps and an isolated proof-of-concept. We commit to acknowledging receipt within 12 hours, issuing immediate hotfixes, and respecting a standard 90-day coordinated disclosure period.

Immediate Self-Service Answers

Technical Support Knowledge Base

Before submitting a ticket, check whether your question has already been answered below. These represent the most frequent technical inquiries received by our engineering team.

Why did my browser crash or reload when converting a batch of 150+ photos?
Because all image processing happens 100% inside your device's browser memory (RAM) via WebAssembly, decoding a high-resolution 48-megapixel iPhone photo expands into an uncompressed RGBA pixel buffer of roughly 192 MB per image. If 150 photos are processed simultaneously without garbage collection, the browser process can exceed its 32-bit tab memory allocation ceiling (typically 1.4 GB to 2.0 GB on Chromium and WebKit), triggering an out-of-memory reload. To avoid this, convert batches in sets of 25 to 50 files on systems with under 8 GB RAM, or close background browser tabs.
Can I convert Apple ProRAW DNG files using this converter?
This converter specializes in HEIF/HEIC containers (.heic, .heif). Apple ProRAW images shot on iPhone 12 Pro through iPhone 16 Pro use the Adobe Digital Negative (.dng) raw image specification rather than HEIC. If you attempt to drop a .dng file into the dropzone, the parser will reject the header. To convert ProRAW files, first export them from Apple Photos as full-resolution HEIC or JPEG, or look for our upcoming RAW conversion engine.
Do I need to send my files to your support team to fix a conversion glitch?
No. We strictly recommend against sending sensitive personal photographs. To help us reproduce a parsing anomaly, you only need to provide: (1) your device model and iOS version, (2) the exact camera mode used (e.g. Portrait, Night Mode, Macro, or Live Photo), and (3) your browser brand and build number. We maintain an automated synthetic test suite that generates compliant mock HEIC bitstreams exhibiting those exact container flags without requiring your private images.
Why does a converted PDF look slightly different in saturation on Windows?
Apple devices capture photos using the wide Display P3 color space, which offers a 25% broader chromatic spectrum than standard sRGB monitors. When our converter generates a PDF or raster file, it maps color matrices to sRGB for universal compatibility across standard PDF viewers and office printers. Some older Windows PDF viewers that lack International Color Consortium (ICC) color management profiles may render saturated reds or deep emerald greens slightly differently compared to the calibrated OLED display of an iPhone.
Can our enterprise or school license an offline self-hosted version?
Yes. Educational institutions, legal practices, and healthcare organizations requiring strict intranet deployment or air-gapped compliance can reach out through our contact form under the "Business, API or Partnership Inquiry" topic. We provide turnkey static asset bundles that run on internal HTTP servers without requiring any internet connection or cloud dependency.
How can I contribute translations or test localization accuracy?
We welcome multilingual community contributions! Our internationalization dictionary powers 12 languages. If you spot a technical inaccuracy or awkward phrasing in French, German, Spanish, Japanese, or any other supported language, email us at info@convertheictopdf.com with the topic "General Inquiry / Feedback".
