Compress, convert, and edit — without uploading.
Every image you compress for a website, every photo you crop before texting, every screenshot you upload to a forum — most "free" online tools today take a copy of that file before they hand it back to you. We built every CipherForces image tool to do the work in your browser using canvas APIs and WebAssembly. A 24-megapixel photo from your iPhone, a multi-page TIFF scan, a folder of 80 banner images — all processed on your machine. Nothing leaves the tab. The differentiator matters most for business-card mockups, draft logos, photos of identification documents, and any image you would not paste into a public Discord. The output quality is identical to (or better than) the cloud equivalents because we use the same codecs (mozjpeg, oxipng, WebP, AVIF) without the lossy round-trip through someone else's upload pipe.

Open toolBuilt for privacy, breadth, and speed.
Format coverage you actually need
JPEG, PNG, WebP, AVIF, HEIC, GIF, BMP, TIFF, SVG. HEIC support uses a 3-tier decoder (createImageBitmap → Image.decode → libheif WASM) that works on iPhone, Android, and every desktop browser.
Batch tools that scale
Compress 200 photos at once with the Batch Processor, or use Bulk Rename to standardize filenames. Memory-aware — does not OOM your phone.
Strip metadata before sharing
Photos taken on phones embed GPS coordinates, camera serial numbers, and software fingerprints. Our Metadata Stripper removes them in one click before you upload anywhere.
Squoosh-tier quality, more breadth
Squoosh (the Google project) is the gold standard for browser compression — but it does one image at a time and only one operation. Our toolkit gives you the same compression quality plus crop, resize, watermark, OCR, palette extraction, and 17+ more operations.
People ask these things.
How can I compress images without uploading them anywhere?
Use the Image Compressor — it runs MozJPEG and OxiPNG in WebAssembly inside your browser. Drop in any photo, pick target quality or size, download the smaller version. Nothing transmits.
Can I convert HEIC to JPG on my iPhone?
Yes. The Format Converter handles HEIC natively on iOS Safari (the system decoder; no WASM needed) and falls back to libheif WASM on Android Chrome and desktop browsers. Drop in HEIC, choose JPG, download.
Does this work for batch photo compression?
Yes. The Batch Processor handles up to a few hundred images at once depending on your device memory. Same compression quality applied to each, output as a zip.
