We built NoStorePDF with a strict local-first architecture. It is the definitive privacy-first alternative to iLovePDF, Smallpdf, PDF24, and Adobe Acrobat Online. No hidden servers, no cloud storage, no compromised privacy.
Unlike traditional PDF editors, your files are never uploaded to any remote server. Every single byte remains on your computer throughout the entire process.
We have no databases storing your sensitive documents. Once you close your browser tab, all temporary local processing data is completely erased.
Powered by next-generation WebAssembly (WASM), we bring enterprise-grade processing logic directly into your browser for instant, secure execution.
Compress images online and preserve photo quality. Reduce JPG, PNG, WEBP file size up to 80% without visible loss. No upload — runs in your browser.
Compress JPG, PNG, WEBP, AVIF, HEIC and other images online for free. Reduce image file size without noticeable quality loss using secure browser-based.
Image compression reduces file weight by optimizing image encoding and trimming redundant data so graphics load faster across websites, emails, and messaging apps. Large uncompressed images increase page load times, consume mobile data, and slow down document workflows.
The NoStorePDF Image Compressor runs entirely inside your web browser using HTML5 Canvas APIs and client-side decoders. Your photos and graphics are processed locally in your device's memory—they are never uploaded to remote servers or stored in any cloud repository.
Choosing the best compression strategy depends on how you plan to use your images:
The workspace accepts major image formats directly from your device:
Before saving, use the interactive split-screen slider powered by react-compare-slider to compare the original and compressed images side-by-side. This ensures you can confirm image clarity before exporting.
Queue multiple images simultaneously. The local compression engine processes each image in your browser queue, computes original versus compressed file sizes, and lets you download individual files or a single bundled ZIP archive.
Drag and drop single files or batches of JPG, PNG, WEBP, AVIF, or HEIC images into the workspace.
Select a preset like Web Optimized (75%) or fine-tune quality and output format to match your needs.
Drag the interactive comparison divider to evaluate visual clarity against the original image.
Save individual images or download the entire batch packaged into a ZIP archive.
