कसे वापरावे

  1. एक फोटो बॉक्सवर ओढून सोडा किंवा तो निवडण्यासाठी बॉक्सवर टॅप करा (JPG, PNG, WebP किंवा GIF). फोटो आपल्या डिव्हाइसवरच उघडतो, काहीही अपलोड होत नाही.
  2. पिक्सेल निवडून नवीन रुंदी किंवा उंची टाइप करा (लांबी-रुंदीचे प्रमाण कायम ठेवा चालू असेल, तर दुसरी बाजू आपोआप बदलते), किंवा टक्केवारी निवडून 50% सारखे प्रमाण निवडा.
  3. आउटपुट फॉरमॅट (JPG, PNG किंवा WebP) निवडा, आणि JPG किंवा WebP साठी गुणवत्तेचा स्लायडर सेट करा.
  4. इमेजचा आकार बदला वर टॅप करा. मूळ आणि नवीन मापे आणि दोन्ही फाइल्सचे आकार पूर्वदृश्यासह दिसतात.
  5. नवीन आकाराची इमेज सेव्ह करण्यासाठी डाउनलोड करा वर टॅप करा.

What does an image resizer do?

An image resizer changes the number of pixels in a picture: its width and height. A photo from a modern phone is often 4000 × 3000 pixels (12 megapixels) or larger, which is far more than you need for WhatsApp, an email, a website or most online forms. Making it smaller in pixels also makes the file much smaller, so it uploads faster and takes less space.

This image resizer runs in your browser using the <canvas> element. Your photo is never sent to a server, which matters when it's an ID card, a certificate or a personal picture.

How the aspect ratio is kept

The aspect ratio is the shape of the picture: width divided by height. If you change only one side and leave the other, the picture gets squashed or stretched. With Keep aspect ratio on, the tool works out the other side for you:

New height = New width × (Original height ÷ Original width)
New width = New height × (Original width ÷ Original height)

The result is rounded to the nearest whole pixel. In Percentage mode both sides are multiplied by the same factor, so the shape never changes.

Worked example

You have a 4000 × 3000 photo and want it 1600 pixels wide for a website.

New height = 1600 × (3000 ÷ 4000) = 1600 × 0.75 = 1200 px

The resized image is 1600 × 1200, which is 1.92 megapixels instead of 12: about one-sixth of the pixels. Saved as a JPG at 85% quality, a typical photo of that size is a few hundred KB instead of several MB, though the exact size depends on how much detail the picture has.

Percentage sizes for a 12 MP phone photo

ScaleSize (from 4000 × 3000)Megapixels
100%4000 × 300012.0
75%3000 × 22506.75
50%2000 × 15003.0
25%1000 × 7500.75

Halving both sides leaves only a quarter of the pixels. That's why a 50% resize usually cuts the file size by much more than half.

Choosing JPG, PNG or WebP

FormatBest forTransparencyQuality slider
JPGPhotos; forms and portals that accept only JPG/JPEGNo (becomes white)Yes
PNGScreenshots, logos, text, images with transparencyYesNo (lossless)
WebPWebsites and apps that support it; smallest filesYesYes

The quality slider controls JPG and WebP compression. Around 80–90% looks the same as the original to most people; lower values give smaller files with visible blur or blockiness, especially around text and sharp edges.

Sideways photos are fixed automatically

Phones often store a photo in one direction and add an EXIF "orientation" tag that says how to turn it. Some tools ignore the tag, so the resized picture comes out sideways. This resizer reads the orientation first (using createImageBitmap with imageOrientation: "from-image"), so the output looks the way it does in your gallery. Saving through the canvas also drops other EXIF data, including GPS location.

Tips

  • Avoid enlarging. Making a small picture bigger can't add detail. It only makes it softer.
  • Resizing vs compressing: resizing reduces pixels; compressing lowers quality at the same pixel size. If you need a file under a fixed KB limit, use the Image Compressor's target-size mode.
  • Exam and government forms usually need an exact pixel size and a KB range. Use the Exam Photo & Signature Resizer, which crops and compresses to both at once.
  • Very large outputs may fail on phones: iPhone browsers cap a canvas at about 16.7 megapixels (for example 4096 × 4096).

No. The image is opened and resized inside your browser using the canvas feature. Nothing is sent over the internet, so it's safe for ID cards, certificates and personal photos, and it works even on a slow connection once the page has loaded.

Leave 'Keep aspect ratio' switched on and type only the width or the height. The tool calculates the other side as new height = new width × (original height ÷ original width), so a 4000 × 3000 photo resized to 1600 wide becomes 1600 × 1200.

Yes, a lot. File size depends mainly on the number of pixels, and halving the width and height leaves only a quarter of the pixels. For a fixed KB limit, use the Image Compressor's target-size mode, which also lowers quality and shrinks dimensions until the file fits.

Because phones often store photos sideways with an EXIF orientation tag, and some tools ignore it. This resizer reads that tag first, so the result is the right way up, just as it appears in your gallery.

Use JPG for photos and for government or exam portals, which usually accept only JPG/JPEG. Use PNG for screenshots, logos and images that need a transparent background. Use WebP for websites; it gives small files but a few older apps and portals don't accept it.

Yes, by entering a larger size or a percentage above 100%, but enlarging can't create detail that wasn't captured, so the result will look softer. Start from the largest original you have.
