Features & How It Works
100% Private Processing
All image compression happens locally on your device. This tool is completely private, and your files and photos never leave your device.
Fast Batch Compression
Compress multiple photos at the same time with smooth, rapid performance that keeps your screen responsive and saves you time.
Flexible Quality Control
Choose from High Quality, Balanced, or Max Compress presets, or fine-tune with the slider to achieve your desired balance between image fidelity and file size reduction.
Clear File Savings Summary
View exact before-and-after file sizes and percentage saved immediately once compressed, showing you precisely how much storage space you reclaimed.
No Count or Size Limits
Batch compress as many images as you need with no file count limits. Everything processes directly on your device with zero queue times.
Format Optimization
Lossless PNG formats automatically convert to high-fidelity lossy WebP formats if compression quality is under 100%, shrinking sizes by up to 80%.
Frequently Asked Questions
Where are my images processed? Are they uploaded to a server?
No, your images are never uploaded to any server. This tool is completely private, and your files and data never leave your device. This guarantees complete privacy and security for all your photos.
Which image formats are supported?
This tool supports compressing standard image formats including JPEG, PNG, WebP, and GIF files.
Can I compress multiple images at once?
Yes! You can select or drag and drop multiple images at the same time. The tool compresses multiple photos concurrently on your device without causing the interface to freeze or lag.
How does the quality slider affect the final file size?
The slider sets the compression ratio. Selecting a lower quality percentage (such as 35% or High compression) compresses the file further, yielding a much smaller file size, but may introduce minor visual artifacts. Setting it to a higher quality (such as 85% or Low compression) preserves original details but produces a larger file.
Does compressing a PNG convert it to WebP?
Yes, for PNG files, if the compression quality slider is set below 100%, the compressor automatically outputs a WebP image. This is because PNG is a lossless format that cannot be lossily compressed. Converting to WebP enables massive file size savings (often 80%+ smaller) while maintaining excellent visual quality.
Is there a file size limit for image uploads?
There is no artificial limit on the number or size of images you can select. However, because compression is done locally on your machine, very large images (e.g. 50MB+ or high-megapixel photos) will consume more system memory during processing.
Will compressing my photos reduce their visible quality?
Our smart compression algorithms remove unnecessary image metadata and optimize pixel data to significantly reduce file sizes while maintaining excellent visual sharpness. You can also adjust the quality slider to find your perfect balance between file size and visual clarity.
