Features & benefits
Image resizing for uploads, email and the web
Choose a target that matches the destination, not just smaller dimensions. The preview lets you check file size and visible quality together.
Limit pixel dimensions
Set maximum width and height so large photos do not load more pixels than the destination needs.
Choose format and quality
Compare JPG, PNG and WebP and balance visual quality against file weight.
Local and upload-free
Processing runs in the browser. Image content is not sent to BTradeTech.
How it works
A clear workflow
Resize and compress JPG, PNG and WebP images to a target file size or maximum dimensions. Image processing happens locally on your device.
Practical example
Choose 500KB or 1MB for lighter email attachments, or 100KB and 200KB when an application or upload portal sets a strict limit.
Practical guide
Choose an image size for the real destination
A KB target controls file weight; maximum pixel dimensions control how large the image can be displayed.
Common use cases
For strict upload limits, profile pictures or compact thumbnails.
For forms, application portals and lightweight website images.
For good screen quality with manageable loading and email size.
For larger email photos or more detailed presentation images.

Limits & transparency
Realistic expectations
The achievable size depends on image detail, dimensions and format. JPG and WebP usually compress more efficiently than PNG. The tool aims for the target without claiming an exact byte-for-byte result.
FAQ
Frequently asked questions
How do I resize an image to 100KB?
Choose an image, enter 100 as the maximum size and start processing. Review the preview, dimensions and actual output size before downloading.
Can I compress an image to 200KB, 500KB or 1MB?
Yes. Enter 200, 500 or 1024KB. For large photos, the tool adjusts quality and may reduce pixel dimensions when needed.
What image size works for email?
500KB to 1MB per image is often a practical starting point, but the total attachment limit depends on your email provider and the number of files.
Are my images uploaded?
No. Processing runs locally in the browser and image content is not sent to BTradeTech.
Why is the result not always the exact target size?
Compression depends on image content. The tool gets under or close to the target, but not every format can produce an exact byte count.
