About This Tool
ConvertXpert's image resizer online makes it simple — upload your photo, set the width and height in pixels, download. That's it.
Every phone camera today shoots at 3000x4000 pixels and higher. That's fine for printing, but a problem when you're uploading a photo online.
Government portals are strict about dimensions. Aadhaar wants 200x200. Passport Seva wants 630x810. SSC application forms specify 100x120. Upload the wrong size and the form throws an error — or worse, silently rejects the file without telling you why.
No account needed, no watermark, and your photo stays on your device the entire time — nothing gets uploaded anywhere.
How to Resize Image in Pixels — 3 Steps
Upload Your Image
Click the upload area or drag your photo on the tool. Both JPG and PNG work. Most phone photos upload fine just like they are. No need to convert anything first.
Set Width and Height
Enter width and height in pixels. The aspect ratio lock is on by default — change one value and the other adjusts automatically to avoid distortion. If you want a specific fixed size no matter the proportions, turn it off.
Download
Click resize and download your picture. The output is the same format – JPG stays JPG, PNG stays PNG. Instant file downloads to your phone or tablet.

Resize Image in Pixels vs Reducing KB — What's the Difference?
This is the part that most tools don't do, and that's why people get confused.
When you resize image in pixels you are changing the dimensions of the image. How wide it is. How tall it is. A 4000x3000 pixel turns to 800x600 pixels. It is physically smaller in size, and the file size usually gets smaller as a result. But the pixel resize has to do with dimensions, not file size.
When a government portal says "photo must be under 50KB" or "under 200KB", that is a size requirement, not a pixel requirement. You may need to do both – change image width and height online to the correct pixel dimensions first and then compress to meet the KB limit.
• Aadhaar portal asks for photo under 50KB at 200x200 pixels
• Step 1: Resize image to 200x200 pixels using this tool
• Step 2: Compress the resized image to under 50KB using Image Compressor
Many people try to just compress the image and wonder why the portal still rejects it. Both steps matter.
When Do You Need to Resize an Image?
Government and exam portals
UPSC, SSC, banking exam, and most government job application portals have strict photo size requirements — usually 100x120 or 200x200 pixels with a file size limit. Phone camera photos are usually 3000x4000 pixels or larger — they need to be resized before uploading or the portal will reject them.
WhatsApp and social media
A 4MB photo sent on WhatsApp gets compressed automatically and ends up looking blurry. Resize it to 500x500 pixels before sending and it looks clean on every screen.
Website and blog images
Large images slow down websites. A product photo straight from a camera can be 5-6MB. Resize it to the actual display dimensions — usually 800x800 or 1200x630 — and the page loads faster.
Passport and document photos
Passport Seva requires 630x810 pixels. Aadhaar requires 200x200. Most phone photos are not these sizes. Resize image online to the exact dimensions needed instead of guessing.
Email attachments
Most email servers have attachment size limits. A set of 10 wedding photos from a phone can easily be 80-100MB total. Resize each to 1200x800 and the same set becomes 10-15MB — easy to send.
Frequently Asked Questions
An image resizer online is a browser-based tool that lets you change the width and height of a photo in pixels without installing any software. You upload your image, enter the dimensions you need, and download the resized version. ConvertXpert's resizer processes your photo entirely inside your browser — nothing is sent to any server.
Upload your JPG or PNG to the tool. Type the width and height in pixels — for example, 800 wide and 600 tall. The tool resizes the image to those exact dimensions and gives you a download link. Takes about 10 seconds.
Upload your JPG to ConvertXpert's image resizer. Set the width and height in pixels. Click resize and download. The output is a JPG file at the exact dimensions you entered. No signup, no watermark, no limit on how many times you use it.
Same process as JPG. Upload your PNG, set the pixel dimensions, download the resized PNG. The tool keeps the PNG format and does not convert it to JPG unless you ask it to.
Upload the image, type the new width in the width box and the new height in the height box. If aspect ratio lock is on, changing one value automatically adjusts the other. Turn off the lock if you need fixed dimensions regardless of the original proportions.
WhatsApp displays profile photos at 500x500 pixels. Upload your photo, resize it to 500x500, and it will display clearly on all phones without any auto-compression blurring.
Aadhaar portals typically require photos at 200x200 pixels under 50KB. Resize your photo to 200x200 pixels using this tool first, then use the Image Compressor to bring it under 50KB.
Passport Seva requires a photo of 630x810 pixels in JPEG format, between 10KB and 250KB. Resize your photo to 630x810 using this tool, then check the file size. If it is over 250KB, compress it using the Image Compressor.
Scaling down — making an image smaller — does not noticeably reduce quality. Scaling up — making an image larger than its original size — can cause blurring because the tool has to add pixels that were not there. For best results, only scale up by 1.5x or less.
Pixels control the dimensions — how wide and tall the image is. KB controls the file size — how much storage it takes. Resizing to smaller pixel dimensions usually reduces the KB too, but not always to a specific target. To hit an exact KB limit, use the Image Compressor after resizing.
Your photo never leaves your device. All processing happens inside your browser. ConvertXpert does not upload, store, or access your images at any point.
The tool supports JPG and PNG — the two most common photo formats. Both can be uploaded and downloaded in the same format. Most phone photos are JPG and most screenshots are PNG.
