How Can We Help?

We support the following image formats:

• JPEG/JPG - Most common for photos
• PNG - Best for graphics with transparency
• WebP - Modern format with excellent compression
• BMP - Uncompressed bitmap images

You can also convert between formats during compression.

It depends on the compression level you choose. Our tool offers adjustable quality settings:

• High quality (80-100%): Minimal visible quality loss, moderate file size reduction
• Medium quality (60-80%): Good balance between quality and file size
• Low quality (30-60%): More visible quality loss, maximum file size reduction

We recommend testing different settings to find the right balance for your needs. The default 80% quality typically provides excellent results for web use.

Individual images can be up to 50MB in size. For batch processing, you can compress up to 10GB total across all files.

These limits are based on browser capabilities and ensure optimal performance. Larger files may take longer to process depending on your device.

Yes! Our Batch Compressor tool allows you to compress multiple images simultaneously. Simply select multiple files or drag and drop them all at once. You can then download all compressed images as a ZIP file.

We support these popular video formats:

• MP4 - Most widely compatible format
• MOV - Apple QuickTime format
• AVI - Windows video format
• WebM - Web-optimized format
• MKV - High-quality container format

Individual videos can be up to 500MB in size. For batch processing with multiple videos and images combined, the total limit is 10GB.

Processing time depends on video length, resolution, and your device's capabilities.

Compression time varies based on several factors:

• Video length: Longer videos take more time
• Resolution: 4K videos take longer than 720p
• Device power: Newer devices process faster
• Quality settings: Higher quality takes more time

Typically, a 5-minute 1080p video takes 2-5 minutes to compress on a modern device.

No, never! This is the core principle of Snapshrink. All compression happens entirely in your web browser using client-side technologies. Your files:

• Never leave your device
• Are never uploaded to our servers
• Are never seen or accessed by us
• Remain completely under your control

You can even disconnect from the internet after the page loads and continue compressing.

By default, our compression process may remove some metadata to reduce file size. This includes:

• EXIF data (camera settings, GPS location)
• Creation timestamps
• Camera make and model
• Software information

If you need to preserve metadata, we recommend keeping a backup of your original files.

We use minimal analytics (like Google Analytics) to understand how people use our website, such as page views and button clicks. However:

• We never track what files you compress
• We never collect file names or contents
• We never store personal information

See our Privacy Policy and Cookie Policy for complete details.

Once the webpage fully loads, you can disconnect from the internet and continue using the compression tools. The initial page load requires internet to download the necessary code and libraries, but after that, everything works offline.

Yes! Snapshrink is fully responsive and works on smartphones and tablets. However, please note:

• Processing may be slower on mobile devices
• Very large files might cause performance issues
• Some older mobile browsers may have limited support

We recommend using a modern mobile browser like Chrome or Safari for the best experience.

If you encounter errors, try these troubleshooting steps:

• Refresh the page and try again
• Try a smaller file or lower quality setting
• Clear your browser cache and cookies
• Update your browser to the latest version
• Try a different browser
• Ensure you have enough free RAM/memory

If problems persist, please contact us with details about the error.

Yes, we strongly recommend it! Always keep backups of your original files before deleting them. While our compression is high-quality, it's always best to have the original in case you need it later for different purposes or higher quality outputs.

Currently, we don't offer a public API. However, our compression tools are built using open-source libraries that you can integrate into your own projects. For business inquiries or custom integration needs, please contact us.
