Frequently Asked Questions
Does Shrinky Studio upload my images?
No. Shrinky Studio processes images locally in your browser using browser image APIs. Your images are not uploaded to Shrinky Studio servers for compression.
Which image formats can I compress?
Shrinky Studio is designed for common browser-readable formats including JPG, JPEG, PNG, and WebP. Output options include WebP, JPEG, PNG, and an automatic recommendation.
Is Shrinky Studio free?
Yes. The image compressor is free to use and does not require an account or signup.
Can I compress multiple images at once?
Yes. You can add multiple image files, review the original and compressed sizes, and download optimized images from the file list.
Will compression reduce image quality?
Lossy formats such as JPG and WebP can reduce file size by changing some image data. Use the quality slider to choose the balance between smaller files and visible clarity.
Why did Shrinky keep my original file?
If re-encoding would make a file larger than the original, Shrinky Studio keeps the original so you do not download a heavier image by accident.
Should I choose JPG, PNG, or WebP?
Use JPG for photos and broad compatibility, PNG for lossless-style graphics or transparency, and WebP when you want modern compression with strong size savings.
Can I use Shrinky for website images?
Yes. Shrinky Studio is useful for reducing page weight before uploading images to a CMS, ecommerce store, portfolio, blog, or landing page.
Can I reduce image size for WhatsApp?
Yes. Compressing images before sharing can make files easier to send while letting you keep control over the final download.
Does Shrinky remove EXIF or photo metadata?
Browser re-encoding generally creates a new optimized image file and may not preserve camera metadata. Keep your originals if metadata is important.
Do I need to install software?
No. Shrinky Studio runs in a modern web browser, so there is no desktop app to install.
Is local browser compression good for private files?
It is a strong privacy-friendly workflow because selected images stay on your device during compression. You still control where you save or share the optimized downloads afterward.
