Frequently Asked Questions
Is my image uploaded to a server?
No. All resizing happens entirely in your browser. Your files never leave your device and are never sent to any server.
Which resize modes are available?
Enter the target width, height, or both. Enable Lock Aspect Ratio to maintain proportions automatically. You can also enter a percentage to scale by a fixed factor.
Will resizing reduce image quality?
Enable Lock Aspect Ratio before entering your target dimension. The tool automatically calculates the other dimension to keep the original proportions.
Can I resize to an exact pixel size?
Yes, completely free. No account required, no usage limits, no watermarks.
Is Tracelyx Resize free?

How to Use Tracelyx Resize: A Complete Guide
Resize an Image in 3 Steps
- Upload your image — Drop a JPEG, PNG, or WebP file. The tool shows the current dimensions so you know your starting point before making any changes.
- Set your target dimensions — Enter a width, height, or both. Lock Aspect Ratio keeps proportions correct automatically. You can also resize by percentage for a quick 50% or 200% scale.
- Download the resized image — Choose your output format (JPEG, PNG, or WebP) and click Download. The resized file is saved directly to your device.
Setting Dimensions for Common Use Cases
Social media platforms each have preferred image sizes. Twitter and X work best with 1200×675px for link cards and 1500×500px for headers. Instagram supports square images at 1080×1080px and portrait at 1080×1350px. LinkedIn article images perform well at 1200×627px. Email campaigns typically use 600px-wide images to display correctly in common clients. Entering these values in Tracelyx Resize gives you a pixel-perfect output for the platform.
For print, the target resolution depends on the output size and printing method. Standard print at 300 DPI requires 2480×3508px for A4, and 3508×4961px for A3. If you know the DPI and print size, multiply them to get the pixel count you need. Tracelyx Resize handles any pixel dimension — there is no maximum.
Privacy: Processing Stays in Your Browser
Tracelyx Resize processes your image entirely in your browser using the HTML Canvas API. No file is uploaded — the resize operation runs locally, and the output is downloaded directly to your device. Your image never touches a Tracelyx server.
This matters when you are resizing confidential images: product photos before announcement, client images under NDA, medical images, or personal photographs. No cloud service sees your file — it stays on your device throughout the entire process.
