About ExamMint Resizer
ExamMint Resizer is a specialized tool designed to help Indian students prepare their documents for online applications. We understand the frustration of having forms rejected due to incorrect photo dimensions or file sizes.
Our mission is to simplify this process. By leveraging modern Rust & WebAssembly (WASM) technologies directly in the browser, we provide a lightning-fast, secure, and accurate way to resize photos and signatures without them ever leaving your device.
Privacy & Local Processing
ExamMint Resizer is built with a strict "Privacy First" architecture. Unlike other online tools, we do not upload your photos to any server. All image processing (resizing, cropping, compression) runs locally on your device via our high-performance **Rust & WebAssembly (WASM)** core. This means your sensitive exam documents strictly remain yours, are processed securely in your browser, and never leave your computer or phone.
Device Compatibility & Limitations
Because all processing happens in your browser to protect your privacy, performance directly depends on your device's capabilities.
- Smart File Limits: To ensure smooth
performance and prevent crashes, we automatically
adjust the maximum file upload size based on your
device's available memory (RAM):
- 6MB Limit: For devices with 2GB RAM or less (older phones).
- 10MB Limit: For devices with 4GB to 6GB RAM (mid-range phones).
- 15MB Limit: For devices with 8GB+ RAM (high-end phones & PCs).
- Older Mobile Devices: Very old Android or iOS devices might process images slower than modern desktops or phones.
- Browser Storage: We use your browser's temporary storage to save your progress and settings. Clearing your browser cache will reset the app state.
Latest Updates & Features
Rust & WebAssembly Migration
We have migrated our entire image processing pipeline to Rust and WebAssembly (WASM). By compiling native Rust code to WebAssembly, image resizing (using Lanczos3 resampling), cropping, and high-performance compression now run directly inside your browser at near-native speeds. This yields 5-10x faster execution and improved memory safety, especially on lower-end mobile devices.
HEIC/HEIF Support
We now fully support .heic and .heif image formats, commonly used by iPhones and iPads. You can directly upload these images without needing to convert them first.
Improved Wasm-based Compression
We've upgraded our compression engine using WebAssembly to ensure your photos meet the strict KB size limits of exams like UPSC and SSC without losing visual clarity.
Offline Capability
ExamMint Resizer works offline once loaded. You can bookmark it on your phone or computer and use it even without an Internet connection.
