Is ImgCrush really 100% free?
Yes. ImgCrush is completely free to use with no hidden costs, no sign-up required, no daily limits, and no watermarks added to your images. The service is supported by non-intrusive advertisements.
Are my images uploaded to your server?
No. All image processing happens entirely within your web browser using JavaScript and the HTML5 Canvas API. Your images never leave your device. You can even use ImgCrush completely offline once the page is loaded.
What image formats does ImgCrush support?
ImgCrush accepts JPG, JPEG, PNG, WebP, AVIF, and GIF files as input. You can convert images between JPG, PNG, WebP, and AVIF formats. Note that animated GIFs will lose animation when processed.
Can I compress an image to a specific file size like 100 KB?
Yes! In the Compress tab, enter your desired maximum file size in KB (for example, 100 KB) and ImgCrush will automatically find the best quality setting using a smart binary search algorithm to reach that exact size.
How is EXIF metadata removed?
When you upload an image, we re-render it through an HTML5 canvas, which discards all EXIF metadata in the process. This removes GPS location, camera information, timestamps, and any other embedded data, producing a clean image safe to share.
What's the difference between JPG, PNG, WebP, and AVIF?
JPG is best for photos with many colors. PNG supports transparency and is best for graphics with text. WebP offers 25-35% better compression than JPG and PNG with similar quality. AVIF is the newest format with even better compression but slightly less browser support.
Is there a limit on file size or number of images?
There are no artificial limits set by ImgCrush. Practical limits depend only on your device's memory. Most modern devices can handle batch processing of hundreds of images at once.
Does ImgCrush work on mobile phones?
Yes. ImgCrush is fully responsive and works on iPhone, iPad, Android phones, and tablets using any modern browser (Safari, Chrome, Firefox, Edge).
How much can I reduce my image file size?
Results vary by image type and content. Typically, JPG images can be reduced by 40–80% with minimal visible quality loss. PNG files with large areas of flat color can often be reduced by 60–90%. Converting JPG to WebP typically saves an additional 25–35%.
What is WebP and should I use it?
WebP is a modern image format developed by Google that provides superior compression compared to JPG and PNG. It is supported by all major browsers including Chrome, Firefox, Safari, and Edge. If you're optimizing images for a website, converting to WebP can significantly improve your page load speed and SEO performance.
Can I resize images to specific social media dimensions?
Yes! In the Resize tab, select "Preset sizes" to choose from popular dimensions including Instagram Square (1080×1080), Instagram Portrait (1080×1350), Facebook/OG Image (1200×630), Twitter Header (1500×500), and YouTube Thumbnail (1280×720).
Does image compression reduce quality?
It depends on the compression level. Lossy compression (like JPEG) does reduce some image data, but at moderate quality settings (70–85%) the difference is barely visible to the human eye. Lossless compression (like PNG optimization) preserves all image data while still reducing file size. ImgCrush lets you choose your quality level so you control the tradeoff.
What is EXIF data and why should I remove it?
EXIF (Exchangeable Image File Format) data is metadata automatically embedded in photos by cameras and smartphones. It can include your exact GPS location, the device model and serial number, the date and time the photo was taken, camera settings, and sometimes even your name. Removing EXIF data before sharing photos online protects your privacy and prevents others from tracking your location.
Is ImgCrush safe to use with sensitive photos?
Yes. Because all processing happens locally in your browser with no server uploads, ImgCrush is safe to use with sensitive, private, or confidential images. Your photos never travel over the internet during processing, and they are never stored anywhere outside your own device.
