What "local processing" actually means here
Most online image compressors work by uploading your file to a server, compressing it there, and sending back a result. QuickTiny doesn't do that. Compression happens in your browser using the HTML canvas API: your image is drawn onto a canvas element and re-exported at a lower quality, entirely on your device. The file never leaves your browser as part of that process.
How it works
- Choose an image (or, with Batch Pro, several at once).
- Your browser draws it to a canvas and re-encodes it locally — no network request carries the image data.
- Download the compressed file directly from your browser.
What does touch a server
Two things, and neither is your image: loading the page itself (like any website), and, for Batch Pro, the one-time PayPal payment used to unlock it. PayPal handles that payment directly — QuickTiny's server creates and confirms the order through PayPal's API and never sees your card details, and your images are not part of that request at all.
Free tool vs. Batch Pro
The free Image Compressor handles one image at a time, no payment or account needed. Batch Pro ($4.99 one-time) is the same local processing, extended to handle many images in one pass.
Good fits for this
- Personal photos you don't want passing through a third-party server
- Work or client images under confidentiality
- Anyone who'd rather not upload files to an unfamiliar site just to resize them
- Situations where you're offline or on an unreliable connection — no upload required
Frequently asked questions
Is any part of my image ever sent to a server?
No. The compression itself happens entirely in your browser. The only network activity related to Batch Pro is the PayPal payment step, which doesn't include your image files.
How can I verify this myself?
You can open your browser's network tab while compressing an image and confirm there's no outgoing request carrying the file. This is a reasonable thing to check before trusting any "private" claim.
Does QuickTiny store my images anywhere?
No. There's no server-side storage for images at all — nothing to store, since they never leave your device during compression.
Is this a subscription?
No. QuickTiny Pro is a single one-time payment of $4.99 that unlocks batch compression permanently in that browser.
Where can I read the full privacy policy?
See the Privacy page for the complete details on what QuickTiny does and doesn't collect.
Is this GDPR-friendly?
Since your images are never transmitted to or stored on a server, there's no image-related personal data being processed by QuickTiny to begin with. This isn't legal advice — if you need a formal compliance statement for your organization, review the specifics with your own counsel.
