Alternatives (and when to pick them)
- Desktop apps — best for heavy daily editing with lots of files
- OS built-ins — fine for occasional jobs when you already know the workflow
- Upload-based websites — convenient, but avoid for sensitive inputs
- Toolkase browser tools — fast, private-by-default for one-off and recurring light work
Tips for private image edits
- Start with a copy of important photos so you can redo settings.
- On phones, very large camera originals may be slow — try a smaller export first.
- Strip location metadata before sharing travel or home photos when privacy matters.
- Convert to WebP or compress after resizing for the smallest shareable file.

FAQ-driven decisions
If you only remember one thing: for file tools, prefer no-upload processing. Then use Image Resizer when the job matches.
FAQ
- Is my image uploaded?
- No. Resizing uses an on-device canvas.
- Will quality change?
- Enlarging can look soft; shrinking is usually fine. Output keeps the source format when possible.
- Does Toolkase upload my files when I use Image Resizer?
- No. Image Resizer is privacy-critical: processing stays on your device and files are not uploaded to Toolkase servers for this workflow.
- Is Image Resizer free on Toolkase?
- Yes. Image Resizer runs in your browser with no account required.
- Do I need to install software to use Image Resizer?
- No. Open the tool page in a modern browser and work there — nothing to install.
