How to use the Image Resizer

Press the box above and choose one photo or many.
Pick Pixels, Percent (200% = twice as big) or cm / inch and type the width and height. Type only one and the other is worked out for you.
If a form needs a file size, fill in File size (for example at most 100 KB).
Press Change size, then download each photo, or all of them as a ZIP.

How do I make a photo bigger?

Choose Percent and tap 200%, or type a bigger width in Pixels. The photo gets larger, but a computer cannot add new detail, so a very small photo will look softer.

My form needs a photo between 20 KB and 50 KB.

Type 20 in At least and 50 in At most, with KB chosen, and save as JPG. If it still does not fit, tick Allow smaller pixels.

I need exactly 35 × 45 mm.

Open cm / inch, tap Photo 35×45 mm and keep DPI at 300. It uses Crop edges, so the face is not stretched.

My iPhone photo (HEIC) will not open.

Most browsers cannot read HEIC. Safari can. Otherwise change the camera to Most Compatible (JPG) or share the photo as JPG.

Is my photo uploaded?

No. Everything happens inside your browser, on your own device.

How to compress an image to 90 KB

Press the box above and choose one photo or many photos from your phone or computer.
Type the size you need in KB, or tap a quick size such as 50 KB or 100 KB. The default is 90 KB.
Compression starts at once. When it finishes, download each image, or all of them together as a ZIP file.

Why does the image stay sharp?

The tool first tries your picture at its full size and high quality. Only if the file is still too big does it lower the quality a little, and only after that does it reduce the dimensions in small steps. This way the result keeps as much detail as the size limit allows.

FAQ

Are my images uploaded?
No. Everything happens inside your browser, so your photos stay on your device.

Is there a watermark?
No. Compressed images are clean and free.

Which format should I choose?
Choose JPG for passport photos, CNIC copies and online forms, because every website accepts it. WebP gives smaller files but some forms do not accept it. PNG keeps full quality, so the tool shrinks the dimensions instead to reach your size.

What if it says it could not reach the target?
Very large or very detailed images may need a bigger target. Try a larger KB value, or use a smaller original photo.

My image is already smaller than the target.
Then it is kept as it is, with no loss of quality.
