Frequently Asked Questions
How much can I reduce file sizes with this tool?
File size reduction depends on the original image and quality settings. Typically, you can achieve 30-70% size reduction while maintaining good visual quality. JPEG images at 80% quality often reduce to 40-60% of original size, while PNG compression varies based on image content.
What's the difference between the quality levels?
Quality levels range from 10% (maximum compression, lowest quality) to 100% (minimal compression, highest quality). For web use, 60-80% provides good balance. For archival purposes, use 90-100%. Lower settings create smaller files but may introduce visible compression artifacts.
Are my images stored or uploaded anywhere?
No, your images are completely safe and private. All compression processing happens locally in your web browser using JavaScript. Your images are never uploaded to our servers or stored anywhere online. The entire process is client-side for maximum privacy and security.
Can I compress images in different formats?
Yes! We support JPEG, PNG, WEBP, HEIC, and GIF formats. HEIC files (from iPhones) are automatically converted to JPEG for better compatibility. You can upload mixed format batches and each will be compressed using appropriate algorithms for that format type.
What's the maximum number of images I can compress at once?
You can compress multiple images simultaneously, but the practical limit depends on your device's memory and processing power. For best performance, we recommend processing 10-20 images at a time. Larger batches may slow down your browser or cause memory issues on older devices.
Does this work on mobile devices?
Absolutely! The compression tool is fully responsive and works on smartphones and tablets. You can upload photos directly from your device's camera or photo library. However, processing large batches may be slower on mobile devices due to hardware limitations.
Will compression affect image resolution or dimensions?
No, this tool only reduces file size through compression algorithms - it doesn't change image dimensions or resolution. Your images will maintain the same width and height in pixels. If you need to resize images, you would need a separate image resizing tool.
