Image Utility Tools
Check one image or a batch before upload. See exact bytes, KB or MB, format, width, height, aspect ratio, orientation, pixel count, and whether each file meets your limits.
Read file size, format, width, and height locally.
Optional: set one or more maximums. Every result will show whether it passes.
Your images are processed locally in your browser and are not uploaded to our server.

Check the original file against your upload requirements before changing it. A file that already meets the size and dimension limits may not need compression.
Your image stays unchanged. Compare exact bytes, pixel dimensions, and format to identify which requirement needs attention.
The checker reads selected images in your browser and reports the details upload forms care about: exact bytes, file size in KB or MB, pixel width and height, detected format, aspect ratio, orientation, and megapixel count. It accepts JPG, PNG, WebP, GIF, SVG, AVIF, and BMP when the current browser can decode the file. That makes it both an image dimensions checker and an image size finder for files already on your device.
Choose one image or drag in several files at once. Each readable file gets a result card with its exact byte count and formatted size. The default uses 1,000 bytes per KB and 1,000,000 bytes per MB. Set the maximum file size, width or height required by your form and inspect every pass or fail reason; compare exact byte counts if the destination uses a different definition of KB. You can paste a screenshot when the browser exposes it as an image file, and copy the batch as tab-separated results for a spreadsheet or upload checklist. Checking does not change the files.
Check the image first when a form lists more than one rule, such as at most 100,000 bytes and no wider than 600 pixels. Enter the stated limits and inspect each result. If the original already meets them, it may not need any processing. If you need to compress an image or compress JPEG photos to reduce the weight, use a target-KB compressor and check again afterward: it preserves proportions but can reduce dimensions. For exact pixel requirements, prepare the size and crop in an image editor first.
A size checker does not need a server to inspect your image. The browser can read the selected file and decode its dimensions locally, which is faster and safer for personal IDs, certificates, school forms, and document photos. The page gives you the information you need without storing the image, sending it to an API, or making you create an account just to see the file size.
If the file is too large, choose the 20KB, 50KB, 100KB, or 200KB compressor that matches the upload limit. If the portal requires exact pixel dimensions or a particular shape, resize or crop in an image editor first. A KB target alone does not set an exact width or height. After compression, check the downloaded file again because its dimensions and format may have changed.
Image Compressor to 20KB
Use this focused 20KB compressor when a portal rejects anything larger than a very small file. The tool works in your browser and keeps the image on your device.
Open toolImage Compressor to 50KB
Compress an image to 50KB, or prepare a batch for the same upload limit. You can compress JPEG photos, PNG graphics or WebP images locally, then compare each preview, exact byte count and pixel dimensions before downloading.
Open toolImage Compressor to 100KB
Compress an image to 100KB for a photo or document upload limit. You can compress JPEG photos or choose PNG or WebP output, then check the exact size, dimensions and preview. Images stay in your browser during processing.
Open toolImage Compressor to 200KB
Use the 200KB preset when you need a smaller file but still want a clearer photo, screenshot, or document image.
Open toolPNG to WebP Converter
Convert JPG, PNG, or WebP images to a fresh WebP file locally in your browser. Use it when you want a lighter image for web pages, forms, or sharing.
Open toolYes. The image size checker reads the file locally in your browser.
Choose or drag an image into the checker. The result card shows the file size in KB or MB.
Yes. It shows pixel width, pixel height, file size, file name, and format.
No for this task. Both phrases usually mean finding a local image file size and dimensions, so this single page handles both without sending you to a duplicate tool.
Yes. Select or drag multiple supported images, compare them in one place, apply the same size and dimension limits, then copy the batch results.
It supports JPG, PNG, WebP, GIF, SVG, AVIF, and BMP when your browser can decode the file. Animated GIF dimensions refer to the image canvas.
