QBMFX Resize images and target KB
Prepare images for application forms, email and customer upload limits by choosing pixel dimensions and a target file size. The tool searches for a smaller encoded result, then reports the actual downloaded size. Keep the required dimensions and readability in mind: a very small target can be unsuitable for a detailed document or a full-resolution photograph.
Choose your files and review the settings.
Keep originals and inspect the result before printing. File changes clear previous downloads. Heavy image and OCR work can take longer on a phone.
Using Resize images and target KB
- Choose images and enter the required width or height.
- Choose output format, quality and the maximum KB target.
- Generate files, check the actual size and confirm text remains readable.
Behind the result
Resizing changes the pixel dimensions. Lossy compression searches quality settings to approach the requested file size within bounded work; it cannot preserve unlimited detail inside an arbitrarily small file.
Free tools for everyday work
Book centers, photocopy shops, freelancers and developers can use this workspace without a paid plan or account. Files are processed locally. Prepare website resources from offline setup before disconnecting; Urdu/OCR also needs the separate pack above.
The Windows app currently includes the original four tools. These new Book Center tools are available on the website; app and extension updates will be separate releases.
Answers and practical details
Exact file-size limits
Check the downloaded size against the receiving service. Leave a small margin below its limit because KB may mean 1000 bytes or 1024 bytes on different services.
Price and account requirements
This website tool is 100% free. No login, subscription or paid conversion tier is required. Your device supplies the processing memory.
Files and privacy
Input documents and generated results are handled locally. They are not sent to a QBMFX conversion API or stored in a customer database. Website hosting and advertising can still make separate network requests.
Offline preparation
Prepare the website resources from Help while connected, then test the required tool offline. OCR and Urdu text tools also need their optional language or font resources prepared first. Browser storage can be removed by the browser or by you.
Windows app and Edge extension
The existing installed app and extension contain the original four PDF tools. These new Book Center tools belong to the website release; they will need a separate installed-package update.
