Image Compressor & Resizer
Shrink photos and screenshots, resize to exact pixels, and check the saving before you download.
Below about 50% the blurring around text and edges becomes obvious. 70% is a good default for photos.
Shares the figure you see above, with a link back to this calculator. Nothing is uploaded.
- JPEG and WebP are lossy, so the first 30–50% of reduction is usually invisible and anything below 50% quality is not. PNG is lossless, so the quality slider does not apply and re-encoding can even add bytes.
- The image is only ever shrunk. Setting a width larger than the original leaves it untouched rather than blurring it up.
- Transparency is preserved for PNG and WebP. Converting to JPEG fills transparent areas with white, because JPEG has no alpha channel.
- The preview and the download are generated from the same canvas, so the size you see is the size you get.

About the image compressor & resizer
Most rejection emails about an upload come down to file size. Passport photos, exam applications, government portals and job forms all cap images at a few hundred kilobytes, and a phone photo is routinely four to eight megabytes straight out of the camera.
This tool compresses and resizes without uploading anything. Your image is decoded with the browser's own canvas API, which means a 6 MB photo never leaves your device — useful when the picture is an ID document or a signed form.
Drop an image in, then pick a target width or one of the presets that match common Indian requirements, and adjust the quality slider while watching the estimated output size. The preview shows the exact dimensions and the compression ratio before you commit to the download.
Frequently asked questions
What size should a photo be for an online application?
Most Indian exam and government portals want a JPEG under 50–200 KB with the long edge between 600 and 1,200 pixels. Resize to 1,000 pixels on the long edge at about 70% quality and you will usually land comfortably inside that range.
Does compressing an image reduce its quality?
JPEG and WebP are lossy, so yes — but the first 30–50% of reduction is usually invisible on a phone screen and in print at the sizes people actually use. Dropping below about 50% quality is where blurring around edges and text becomes obvious.
Why can a PNG get bigger when I compress it?
PNG is a lossless format, so the quality slider has nothing to trade away. Re-encoding a PNG can even add bytes. For photos, convert to JPEG or WebP instead; keep PNG only for screenshots, logos and anything with transparency or sharp text.
Are my images uploaded to a server?
No. The decoding, resizing and re-encoding all happen in your browser using the canvas API. Nothing is transmitted, and nothing is stored after you close the tab.
What is the difference between resizing and compressing?
Resizing changes the pixel dimensions of the image; compressing changes how much data is used to store those pixels. A passport photo usually needs both: reduce to the required dimensions first, then compress to reach the file-size cap.
