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 photos to 50KB (ID-friendly)
Many online forms cap photo uploads at a few tens of kilobytes, and that cap is often a range rather than a single ceiling. This tool is built for exactly that job: set a 50KB target and it searches for the best quality that still fits, lowering resolution only when there is no other way. Everything runs in your browser — the photo is never uploaded.
Common scenarios with a 50KB limit
| Scenario | Typical limit | Typical format |
|---|---|---|
| Online forms with a 50KB cap | Under 50KB | JPG |
| Email attachments | Under 50KB | JPG |
| Job portal profile photos | 50–100KB | JPG/PNG |
| Social media avatars | Under 50KB | Any |
Photo rules for documents are set by the issuing authority, not by this tool, and they often specify a range rather than a single maximum — some online services also reject files that are too small. Always confirm the current requirements, including any lower size limit, on the official website that handles your application.
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
Made for ID photos
Targets 50KB and outputs a standard JPG or PNG, with no watermark or border added.
Built for ID photos
The goal is the smallest file that still looks clean: quality is lowered as little as possible, and resolution only when the cap demands it — so the photo stays recognizable on the form that requires it.

Fully private
ID photos are sensitive — images never leave your device with this tool.
Frequently asked questions
Will a 50KB photo be rejected?
Not if it meets the country's size, background and format rules. 50KB is a file-size ceiling, unrelated to photo specs; the built-in 5% margin (≈47KB) further reduces rejection risk.
What photo dimensions are required?
Print size and pixel size are two different things, and every authority sets its own rules. Work out the required pixel dimensions from the official instructions for your destination, set them with our image resizer, then compress here. Our guide to passport and visa photo requirements covers the millimetre-to-pixel conversion.
Can I use a selfie photo?
Most countries require a white/light background, front-facing view and open eyes. If your background is cluttered, fix it in an editor before compressing; this tool handles size and format only.
Does the tool check background or head position?
No — it only controls file size. Background colour, head size and centring are separate checks; set those up with a dedicated photo tool first, then compress the result here.
Can I export at a different size than 50KB?
Yes. The same engine offers 20KB, 50KB and 100KB presets plus a custom KB input, so you can prepare multiple versions of one photo for different forms.
Ready to process your ID photo?
Upload, pick 50KB, download — done in seconds. Free, local and private, with no more hunting for a compression tool.
