Image Resizer
Resize photos by pixels, percentage or ready presets for Instagram, YouTube, passport and SSC/UPSC forms — one or many at once.
About Image Resizer
Resize an image online by exact pixels, by percentage, or with ready presets. Presets cover Instagram posts and stories, YouTube thumbnails, passport photos and SSC or UPSC form photos, so you do not have to look up dimensions. When the shape changes, choose Fit, Fill or Stretch and a background colour.
You can resize one photo or many at once and download them as a ZIP. If a form also has a KB limit, resize here first and then use the Image Compressor. All processing happens in your browser, so your photos are never uploaded, and the tool is free with no sign-up or watermark.
How to use Image Resizer
- Drop your photos or try the sample.
- Pick pixels, percentage or a preset size.
- Choose Fit, Fill or Stretch when the shape changes, and a background colour.
- Download each image or everything as a ZIP.
Frequently asked questions
What is the difference between Fit, Fill and Stretch?
Fit keeps the whole photo and adds background bars. Fill covers the whole size and trims the edges. Stretch forces the exact size and may distort the photo.
How are the passport and SSC sizes calculated?
Pixels = size in inches × DPI. 35 × 45 mm at 300 dpi is 413 × 531 px; 3.5 × 4.5 cm at 200 dpi is 276 × 354 px. Always check your notification for the exact size and KB limit.
My form also has a KB limit — what now?
Resize here first, then use the Image Compressor in Target size mode.
How do I resize an image to a specific size in pixels?
Choose the Pixels option, type the width and height you need, pick Fit, Fill or Stretch if the shape differs, and download.
What size should a photo be for SSC or UPSC forms?
Use the SSC / UPSC preset, which sizes the photo at 3.5 × 4.5 cm at 200 DPI. Always check the latest notification, as requirements can change.
