Image resizer — browser-only (private)
Shrink a photo before emailing or uploading it, without handing the file to anyone. Choose a target size, pick a format, and download the result.
Runs in your browser — your input is not uploaded to ToolsNow.
Your files are processed locally in your browser and are not uploaded to ToolsNow.
Processed locally with canvas.toBlob. Metadata such as EXIF orientation and GPS is dropped by design.
How to use
- Drop in an image — anything your browser can open, including HEIC on Safari.
- Pick a resize mode. Fit within a box is the safest default; it never distorts and never upscales.
- Choose format and quality. Lowering JPEG or WebP quality to around 0.75 usually halves the file with no visible loss.
- Watch the preview. It re-renders automatically as you change settings, showing the new dimensions and file size. Press Download when it looks right.
Questions
Is my photo uploaded anywhere?
No. The image is decoded and redrawn by your browser’s canvas. It never touches a network connection, which is why the tool keeps working if you go offline after loading the page.
Why can’t I make an image bigger?
Upscaling invents pixels that were never captured, so it adds file size without adding detail. The tool caps scaling at 100% of the original deliberately.
Which format should I choose?
JPEG for photographs, PNG when you need lossless output or transparency, WebP when you want the smallest file and only modern browsers need to open it.
What happens to EXIF data?
It is removed. Redrawing through a canvas drops all metadata, including camera model and GPS location — useful before posting a photo publicly, but worth knowing if you rely on that data.
