How does the SavirOS image compressor work?

Upload or drag-and-drop images, adjust the quality slider (1-100), select your preferred format (JPEG, PNG, or WebP), and the compressor instantly reduces file size using the browser's native Canvas API. All compression happens locally on your device.

Is the image compressor free and private?

Yes, completely free with no signup required. All image compression happens in your browser — your images never leave your device and are never uploaded to servers. This ensures 100% privacy.

What image formats does the compressor support?

The compressor supports JPEG, PNG, WebP, GIF, BMP, and other standard image formats. You can compress to JPEG, PNG, or WebP output formats, each with adjustable quality levels.

Can I compress multiple images at once?

Yes, the batch compression feature lets you select and compress up to 10 images simultaneously. All images are processed with the same quality and format settings, and you can download them individually.

How much can I reduce file size?

Compression results depend on the original image and quality setting. Most images can be reduced by 30-80%. The compressor shows before/after file sizes and the exact percentage reduction for each image.

About the SavirOS Image Compressor

The SavirOS Image Compressor is a free, privacy-first image optimization tool that reduces file sizes instantly in your browser. Unlike cloud-based services, all compression happens locally on your device — your images are never uploaded to servers. This makes it perfect for professionals who handle sensitive images or simply want faster, more private compression.

How Image Compression Works

Image compression reduces file size by removing redundant or invisible data. The compressor supports lossy compression (JPEG, WebP) which achieves higher compression by discarding minor details the human eye can't perceive, and lossless compression (PNG) which preserves all visual information while reducing file size through better encoding. The quality slider lets you balance between file size and image quality.

Supported Formats

The compressor accepts JPEG, PNG, WebP, GIF, BMP, and other standard image formats. You can output compressed images as JPEG (best for photos), PNG (best for graphics with transparency), or WebP (modern format with superior compression). WebP typically achieves 25-35% smaller file sizes than JPEG at equivalent quality.

Batch Compression

Compress multiple images at once by selecting up to 10 files. Apply the same quality and format settings across all images, then download them individually or all at once. Perfect for optimizing image galleries, product photos, or social media uploads.

Privacy and Security

100% client-side processing means your images never leave your device. No data is uploaded to servers, logged, or retained. This makes the compressor ideal for handling confidential, medical, legal, or sensitive images. No signup required — just open, compress, and go.
