Resize an image

100% private

Upload an image to start. Processing happens in your browser.

Quick answer

Resize image to 450 KB directly in your browser. Upload an image, use the prefilled settings, process it locally, and download the result.

How it works

A 450 KB cap is one of the most common upload limits on government portals, job applications, and exam registration forms. The tool below is already set to 450 KB, so you can drop in a photo and let the compressor find the highest quality that still fits under the limit. Everything runs in your browser, so the original never leaves your device.

  1. Upload a JPG, PNG, or WebP image.
  2. The 450 KB target is already selected.
  3. Choose JPG or WebP for the smallest result, then process the image.
  4. Download the optimized file and upload it wherever it is needed.

Tips for the best result

  • 450 KB is comfortable for most photos at web resolution, so you can usually keep the original dimensions and only adjust quality.
  • JPG gives the smallest size for photographs; keep PNG only when you need a transparent background or razor-sharp text.
  • Save the untouched original separately — once an image is compressed to a hard KB limit you cannot recover the lost detail.

Why this workflow works

Practical benefits

No signup, watermark, or server upload is required.

The relevant dimensions or file-size target are prefilled.

JPG, PNG, and WebP output options cover common workflows.

Common mistakes to avoid

  • Do not edit the only copy of your image. Keep the original before using this page.
  • Do not judge the result by file size alone. Open the downloaded image and check important details.
  • Do not force 450 KB using compression only if the image becomes blurry. Reduce dimensions first when the source is very large.

Example workflows

  • Use this target-size workflow for application portals, support tickets, CMS uploads, or email attachments with a strict file-size cap.
  • If the first result is still too large, reduce the width and height before lowering quality further.
  • If the destination accepts WebP, test it against JPG because it may create a smaller photo file.
