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.
Transparent image — kept as PNG
Compress PNG to 50KB while keeping transparency
Visa applications, passport photos and online form systems in many countries impose a hard limit of around 50KB on photos. This tool is built for exactly that: upload your photo, pick the 50KB target, and the algorithm compresses it to comply while keeping faces and details sharp — fully local, nothing uploaded.
Common scenarios with a 50KB limit
| Scenario | Typical limit | Required format |
|---|---|---|
| Visa & immigration applications | Photo 50KB | JPG |
| Passport & ID photos | 20–50KB | JPG |
| Job portal profile photos | 50–100KB | JPG/PNG |
| Social media avatars | Under 50KB | Any |
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
Face-first compression
The algorithm lowers resolution before quality, maximizing facial sharpness within 50KB so ID photos stay recognizable.
100% private
ID photos are sensitive. Files are processed entirely in your browser and never sent to any server.
One-click compliance
A built-in 5% safety margin compresses a 50KB target to about 47KB, so uploads are never rejected for being just over the limit.
HEIC supported
HEIC photos taken on an iPhone compress directly, with no need to convert format first.
Frequently asked questions
Will a 50KB PNG still be sharp?
Yes. Most ID systems only need a clearly recognizable face. For large originals we prefer lowering resolution over heavy compression, keeping enough pixels to pass automated checks.
Why does PNG need a 50KB target at all?
PNG is lossless, so a 12MP photo can exceed 10MB in its original form. Hitting 50KB requires converting photo areas to a more efficient encoding while keeping edges, text and transparency lossless — the balance this tool automates.
Can I keep transparency in the output?
Yes. Choose PNG or WebP output to preserve the alpha channel. A transparent logo can usually be squeezed to 50KB cleanly; very complex gradients may need 100KB instead.
What is 50KB useful for?
50KB is the sweet spot for ID uploads, web avatars and app assets: small enough to load fast, big enough to stay sharp. Many Asian government and job-portal forms use it as the hard ceiling.
Are my files uploaded anywhere?
No. Compression runs entirely in your browser — your PNG never leaves your device.
