Image Resizer

Resize an image to exact pixel dimensions, scale it by a percentage, or hit a target file size in KB for forms and portals with strict limits. Everything runs in your browser and your image is not uploaded to our servers.

Your media is processed in your browser and is not uploaded to our servers for conversion. Page assets (including the converter engine) still load over the network.

Select or drop an image to resize

JPG, PNG, or WebP. Resize by pixels, percent, or a KB target. Nothing is uploaded.

Click, tap, or drop a file

Your image is processed in your browser and is not uploaded to our servers for resizing.

How to resize an image

  1. Select or drop an image. Choose a JPG, PNG, or WebP file. Its current dimensions and size are shown.
  2. Pick a resize mode. Choose exact dimensions, percentage scale, or a target file size in KB.
  3. Enter your target. Type the width and height, a percentage, or the KB limit you need to stay under.
  4. Click Resize. Resizing runs locally in your browser and finishes in moments.
  5. Check and download. The result shows the new dimensions and real file size. Download it or adjust and resize again.

Image resizer features

  • Resize to a target file size in KB

    Need an image under 100 KB or 50 KB for a form or portal? Enter the target and the tool tunes quality, and resolution when needed, to fit under it while keeping the image as sharp as possible.

  • Exact dimensions or percentage

    Set exact width and height in pixels with an aspect ratio lock, or scale the whole image by a percentage. Enlarging is allowed, with a heads up that upscaled images can look soft.

  • Nothing is uploaded

    Resizing runs on your device using the browser's own image tools. Your photo never leaves the browser, which matters for ID photos and documents.

  • Strips EXIF and GPS metadata

    The resized output is re-encoded from pixels, so hidden metadata such as camera details and GPS location is removed, a privacy bonus when submitting photos online.

How to resize an image to 100 KB or less

Choose the Target file size mode, enter your limit (for example 100 KB, 50 KB, or 20 KB), and pick JPG or WebP output. The tool searches for the highest quality that fits under your limit, and reduces resolution only when quality alone cannot get there.

Strict portals usually also require specific pixel dimensions. If yours does, first resize to the required dimensions, then run the result through Target file size mode if it is still over the KB limit.

JPG is the safest choice for uploads because every system accepts it. WebP is usually smaller at the same quality but a few older portals reject it. PNG cannot be quality-tuned, so it is not offered for KB targets.

Frequently asked questions

How do I resize an image to 100 KB?

Select your image, choose the Target file size mode, enter 100 KB, and click Resize. The tool finds the highest JPG or WebP quality that fits under 100 KB, lowering resolution only if needed, and shows the real final size before you download.

Can I resize an image without uploading it?

Yes. This resizer runs entirely in your browser. Your image is never uploaded to a server, which is important for ID photos, signatures, and documents submitted to forms.

How do I resize an image to exact dimensions?

Choose the Exact dimensions mode and type the width and height in pixels. Keep the aspect ratio lock on to avoid distortion, or turn it off to stretch to the exact size you typed.

Does resizing reduce image quality?

Making an image smaller keeps it sharp. Enlarging an image cannot add detail, so upscaled results can look soft. For KB targets, lower limits force stronger compression, and the tool always keeps the best quality that fits.

Why do forms ask for images under 50 KB or 100 KB?

Portals limit upload sizes to keep storage and processing manageable. Photo and signature uploads for applications commonly require JPG files under a fixed KB limit and sometimes exact dimensions, both of which this tool handles.

Can I enlarge a small image?

Yes. Enter dimensions or a percentage above the original and the tool will upscale. Be aware that enlarging cannot recover detail that is not in the original, so very large enlargements look soft.

Which output format should I choose?

JPG for maximum compatibility with forms and older software, WebP for the smallest files, and PNG when you need lossless quality or transparency at exact dimensions.

Is the image resizer free?

Yes. There is no signup, no watermark, and no limit on how many images you resize.
