75–85% is ideal for web images. 90–95% for print-quality output.
Upload images to start batch compression
Compress hundreds of images at once. Download individually or as a ZIP.
Batch Image Compressor provides client-side image processing powered by browser Canvas and WebAssembly decoders. Compress multiple images at once and download all as a ZIP file. Transformations run entirely in device memory with zero upload lag, ensuring high visual clarity and total data isolation for personal photos, government portal uploads, and digital graphics. Built for zero-latency execution, Batch Image Compressor eliminates network round-trips by computing results directly within your device session. Whether you are running routine batch image compressor workflows or fine-tuning output parameters for compress multiple images at once, all data remains isolated in volatile memory with instant feedback.
Step 1: Upload multiple images
Drag and drop or select multiple JPG, PNG, or WebP files at once. You can add up to 100 files per batch.
Step 2: Set compression quality
Use the quality slider (1–100) to balance file size vs. visual quality. A quality of 75–85 gives good results for most use cases.
Step 3: Review per-file savings
See the compressed size and savings percentage for each image in the preview list before downloading.
Step 4: Download all as ZIP
Click "Download All as ZIP" to get every compressed image in a single archive ready for upload or sharing.
There is no hard limit, but we recommend batches of up to 100 images for smooth browser performance.
Yes. All compression happens in your browser using the HTML Canvas API. Your files never leave your device — nothing is sent to any server.
JPG, PNG, and WebP are supported for both input and output. PNG files are compressed to PNG, JPG to JPG, and WebP to WebP.
No. Compression only reduces file size by lowering quality/encoding efficiency. The pixel dimensions remain unchanged.
It uses the HTML5 Canvas API and compiled WebAssembly decoders to manipulate pixel arrays directly in your browser's local memory.
The compressor balances chroma subsampling and quantization tables to significantly reduce file weight while preserving high perceptual sharpness.
Never. Because files are processed entirely client-side, your images never leave your computer or phone.
Standard web formats including JPEG, PNG, WebP, AVIF, and SVG are supported for input and export.
Yes. You can specify exact target sizes or use preset profiles calibrated for SSC, UPSC, passport, and university admissions portals.
You can process high-resolution images up to standard camera resolutions (24MP to 50MP+), bounded only by your device's available RAM.
