Image Resize in KB – Compress Photo to 20, 50, 100 KB

Reduce Photo Size in KB Online

Online forms in India have strict file size limits. A scholarship portal may want documents below 200 KB, an exam may want the photo between 20 KB and 50 KB, and a government scheme may accept only files under 100 KB. Photos taken on modern phones are usually 2 MB to 6 MB, far above these limits. The free Image Resize in KB tool from Online Wala compresses any image to the exact size you need, right in your browser, without uploading it anywhere.

Features

• One-tap targets: 10 KB, 20 KB, 50 KB, 100 KB, 200 KB, 500 KB and 1 MB.
• Custom range: set both minimum and maximum KB, e.g. 20–50 KB, for forms that reject files that are too small.
• Pixel size: optionally set width, height or both. If you enter only the width, the height is calculated in proportion.
• DPI setting: 72, 96, 150, 200 or 300 DPI written into the JPG file.
• Batch resize: process up to 50 images in one go; each file is downloaded automatically.
• Smart compression: quality is reduced step by step and pixels are reduced only when needed, so the image stays as clear as possible.
• Before/after report showing the original size, new size and dimensions of every file.

How to Resize an Image in KB

1. Tap Choose photos and select one or more images (JPG, PNG or WEBP).
2. Tap a size such as 50 KB, or type your own maximum KB. Add a minimum KB if your form specifies a range.
3. If the form also mentions pixel dimensions, enter the width and height.
4. Tap Resize & download. The compressed JPG files are saved to your phone with the new size in the file name.
5. Check the report table and upload the files to your form.

Common Size Requirements

Different portals use different limits. Many recruitment exams ask for a photograph of 20–50 KB and a signature of 10–20 KB. Scholarship and admission portals often accept documents up to 200 KB or 500 KB. Government scheme portals sometimes allow only 100 KB per document. If your requirement is a PDF rather than an image, use our Image to PDF tool and then PDF Compress. For signatures with a white background use Signature Resize, and for passport photos use the Passport Photo Maker.

Will the Photo Lose Quality?

Every compression removes some detail, but the tool uses the highest quality that still fits your limit. For normal documents and photos, 50–100 KB is enough to remain clear. Very small targets such as 10 KB work best for small images like signatures. If text in a document becomes hard to read, choose a larger KB value or reduce the width to around 1200 pixels before compressing, which keeps text sharp at small file sizes.

Safe and Private

Many websites upload your images to their servers. This tool does not. All processing is done by your own browser, which makes it safe for Aadhaar, PAN, mark sheets and other personal documents.

Frequently Asked Questions

How can I reduce a photo to 20 KB?

Choose the 20 KB chip or type 20 in Max size and tap Resize & download.

My form says minimum 20 KB and maximum 50 KB. What do I enter?

Enter 20 in Min and 50 in Max. If the compressed file is smaller than 20 KB, the tool safely pads it to reach the minimum without changing the picture.

Can I resize many photos together?

Yes, select up to 50 images at once.

Which formats are supported?

JPG, JPEG, PNG and WEBP input. The output is always JPG, which is accepted by almost all portals.

Is it free?

Yes, free and unlimited.

Image Resize vs Image Compression

Resizing changes the number of pixels (width × height), while compression changes how efficiently those pixels are stored. A form may ask for either or both. If the instruction mentions only KB, use compression alone and leave width and height empty. If it mentions pixels such as 200×230, enter them as well. Reducing pixels is the most powerful way to reach very small sizes, while compression keeps the dimensions unchanged. This tool combines both automatically so you always get the clearest possible image at the size you need, whether it is a photo, a signature, a certificate or a screenshot.

Best settings for documents

For certificates and mark sheets, set the width to about 1200 pixels and the maximum to 200 KB; text stays readable while the file stays light.

Conclusion
