Frequently Asked Questions
Is Swiftiny really 100% private and offline?
Yes! Swiftiny performs all image compression completely client-side in your browser. Your images are never uploaded to any server, meaning absolute privacy and instant local processing.
How does the folder structure preservation work?
When you drag and drop nested folders of images, Swiftiny reads the directory hierarchy using the browser's Directory Reader API. After compressing the images, it packages them into a ZIP archive that perfectly replicates your original folder structure.
What is the difference between Standard and Deep compression modes?
Standard mode balances speed and quality for everyday optimization. Deep mode applies stronger analysis to reduce file size further while keeping the output clean and sharp.
Is there a limit on the number of images or file sizes?
The free plan processes up to 50 images per batch. There is still no file-size cap or upload queue, because compression stays on your device. Swiftiny Pro removes the batch limit with a one-time purchase.
