Drop images here or browse files
JPG, PNG, WebP · up to 30 images · you can also paste with Ctrl+VPre-set for you: the target size is 100KB. Add one image or many, press Compress images and download. All other options are in the full Image Compressor.
Where a 100KB limit shows up
100KB is a generous limit, which is why it is used where clarity matters: visa and passport photo uploads on some government sites, supporting documents for applications, school and employee portals, marketplace listings and community forums. It is also a sensible size for photos you send by email or chat, because the recipient can open them instantly on a slow connection.
At 100KB a typical portrait keeps around 800 × 1000 pixels, and a scanned A4 page of text stays readable at roughly 1200 pixels wide.
Compressing to 100KB, step by step
- Drop your images in the box above. JPG, PNG and WebP all work, and you can paste a screenshot with Ctrl+V.
- Keep the target at 100. If you want a specific format for the upload, choose JPEG in Output format; most forms accept it.
- Press Compress images and wait a moment. Large photos take a second or two each.
- Download each file, or use Download all (ZIP) for a batch.
Photos vs. document scans
| Photo (portrait, product) | Scanned document | |
|---|---|---|
| Best format | JPEG | JPEG, or PDF for several pages |
| Typical size at 100KB | 800 × 1000 px | 1200 px wide (A4) |
| Tip | Use a plain background | Scan in good light, crop the edges |
Tips
- For a multi-page document, compress each page here, then combine them with the Images to PDF converter.
- Dark, grainy photos taken at night contain noise that eats bytes. A daylight photo of the same subject compresses far better.
- If a site counts 100KB as 100,000 bytes, set the target to 97 to be safe, because Tolket uses 1KB = 1,024 bytes.
Frequently asked questions
Is 100KB good quality?
Yes, for screens it is. A 100KB JPEG of a normal photo looks clean on phones and laptops. For large prints you would need a bigger file.
Why is my result smaller than 100KB?
Simple images, such as a portrait on a plain wall, reach top quality well under the limit. The tool never adds bytes just to reach 100KB.
Can I compress PDF files to 100KB here?
No, this tool works on images. To make a light PDF, compress the page images here first, then build the PDF with our converter.
