Target size (KB)
A built-in 5% safety margin is applied (e.g. a 50KB target compresses to ≈47KB), so uploads are never rejected for being just over the limit.
Quality 5–100：
Could not reach target size
Lower the quality further or resize the image, then try again.

Compress JPEG to 100KB
JPEG is a lossy format whose file size is driven by compression quality. We binary-search quality from 95% down to 5% to find the sweet spot that keeps files under 100KB with the best possible image quality. Perfect for photos, scans and design files going into online forms — processed locally, no upload, no watermark.
Common scenarios with a 100KB JPEG limit
| Scenario | Typical limit | Required format |
|---|---|---|
| Job application portals | Photo 100KB | JPG |
| E-commerce product photos | 100–500KB | JPG/WebP |
| Scanned document uploads | 100KB–1MB | JPG |
| Design mockups | Under 100KB | JPG |
How to Compress an Image to a Specific Size
Upload your image
Drag & drop an image or click to select. You can upload several images at once.
Set the target size
Pick a preset (20 KB to 1 MB) or type an exact size in KB. The tool auto-adjusts quality and resolution to hit it.
Compress
Click Compress. Everything runs locally in your browser — your files never leave your device.
Download
Download the compressed images one by one, or grab everything as a ZIP.
Why choose this tool
True JPEG optimization
Instead of blindly dropping quality, it tries each quality level and keeps the highest one that fits under 100KB — usually sharper than other tools on the same image.
Other formats too
Although the page focuses on JPEG, PNG, WebP, HEIC and AVIF also compress; output as JPG, PNG or WebP.
Batch upload
Process dozens of product photos or submissions at once and download a ZIP — built for batch workflows.
No upload, no watermark
Images are processed in your browser, never sent to a server and never watermarked.
Frequently asked questions
How does JPEG look at 100KB?
For typical photos (megapixel images squeezed to 100KB) there is some perceptible softness, but it is fine for form uploads and previews. The algorithm picks the highest quality that complies, minimizing loss.
Why JPEG instead of PNG?
For photos, JPEG looks visibly better at the same file size and is accepted everywhere. PNG suits icons or screenshots needing transparency; the tool warns when a transparent image can't hit the target.
Can it compress HEIC?
Yes. iPhone HEIC photos compress directly and can be exported as JPG — perfect for "HEIC from my iPhone, need 100KB JPG" situations.
Will EXIF data (date, location) be kept?
No. Recompressing a JPEG strips most EXIF metadata for privacy and smaller size. If you must keep the original capture date, edit it back in after compression.
Is 100KB enough for a government form?
Usually yes — most government and employer systems accept up to 100KB-200KB. If a form requires less (e.g. 50KB), use the 50KB target instead.
