Target size in KB
Compress an image to 200 KB: for applications, visas and forms
“The file must not exceed 200 KB.” You see that sentence on job portals, university and visa applications and government forms – while a phone photo is 3 MB or more. Here is how to get an image reliably under a fixed limit, and still have it look good.
Start right away: drop your image into the Image Workshop – the target size is already set. It finds the best quality that still fits. Free and without upload.
Compress to 200 KBThe short version
- Drop the photo or scan into the Image Workshop.
- Under “Format & compression”, switch to “Target size” and enter the limit – for “200 KB”, enter 190.
- Optionally choose the “Applications & forms (1200 px)” preset under “Size”.
- Download. The new file size is shown below the image.
Step by step
- Load the image. In the Image Workshop, choose the photo or drag it in. iPhone HEIC photos work too.
- Choose the format. JPG is right for photos and scans – almost every portal asks for it. Use PNG only if it is explicitly required.
- Set the target size. Click “Target size” and enter the limit under “At most (KB per image)”.
- Limit the pixel dimensions sensibly. Under “Size”, set about 1200 px for the longest side. A smaller image at high quality looks better than a huge, heavily compressed one.
- Check and save. Click the image to see the before/after comparison and the file size, then download.
How the target size works: for each image, the highest quality at which the file still fits under the limit is searched step by step. Only if even the lowest quality isn’t enough are the pixel dimensions reduced too – a note on the image tells you when that happened.
200 KB isn’t always 200 KB
Forms mean either 1000 bytes or 1024 bytes by “KB”. The Image Workshop counts like Windows, with 1024 bytes. A file of 199 KB by that count has 203,776 bytes – and a portal that counts 1000 bytes per KB may reject it as “too large”.
Rule of thumb: Always stay about 5% below the limit. For 200 KB enter 190, for 500 KB 475, for 1 MB 970. The Image Workshop links on this page preset 190 KB.
macOS also shows file sizes with 1000 bytes per KB, so the same file looks slightly bigger there than on Windows.
Enter the limit, drop in the image, done – the Image Workshop finds the best quality that still fits.
How many pixels fit into 200 KB?
How large an image can be at a given file size depends on the subject: a portrait against a calm background compresses much better than a photo of foliage or gravel. The values are for JPG and are guidelines:
| Limit | Fits comfortably | Typical use |
|---|---|---|
| 50 KB | up to approx. 600 px | Profile and ID photos in forms |
| 100 KB | up to approx. 900 px | Application photo, membership card |
| 200 KB | up to approx. 1200–1400 px | Job portals, photos for applications |
| 500 KB | up to approx. 2000 px | Scanned documents, certificates |
| 1 MB | up to approx. 2500–3000 px | Multi-page scans, full-screen photos |
Example: US visa photo. The U.S. Department of State asks for a square JPEG between 600 × 600 and 1200 × 1200 pixels and no larger than 240 KB. In the Image Workshop: crop “1 : 1 – square”, longest side 600 to 1200 px, target size 230 KB. Always check the current official requirements for your form – background, head size and lighting matter as much as the file.
Getting scans and documents under the limit
For photographed certificates, letters or IDs, legibility matters more than pretty colors:
- Crop first. Cut away the tabletop and margins – every unnecessary area costs file size.
- 1500 to 2000 px on the long side is enough for a letter or A4 page to keep small print legible.
- Check legibility. Zoom into the before/after comparison. If text looks frayed, lower the pixel dimensions a little and let the quality go up instead.
- Several pages? Many portals then want a PDF. Shrink the images here first, then combine them with JPG to PDF.
When the portal still rejects the file
- Still too large: Lower the limit by another 5 to 10% (see KB vs. KiB above).
- Wrong format: Check the extension. Some portals accept only
.jpg, not.jpeg– rename the file if in doubt. - Minimum pixel size: Some forms also require at least 600 × 600 pixels or similar. Choose exactly those dimensions under “Size” and let the target size adjust the quality.
- “File corrupted” or upload error: Often it’s a HEIC photo that was merely renamed to
.jpg. For a real conversion see HEIC to JPG.

Frequently asked questions
How do I compress a photo to 200 KB?
In the Image Workshop, switch to “Target size” under “Format & compression” and enter 190 KB. The tool automatically finds the highest quality that fits under the limit.
Why enter 190 instead of 200 KB?
Some portals count 1000 bytes per KB, the Image Workshop counts 1024. With about 5% buffer the file fits either way.
Will the image get blurry?
For an application photo with 1200 pixels on the longest side there is no visible difference at 200 KB. If it gets very tight, the tool reduces the pixel dimensions rather than ruining the quality.
Can I compress to 100 KB or 500 KB too?
Yes. Any value from 5 KB upward works under “At most (KB per image)”.
Which format do application portals want?
Almost always JPG, sometimes also PNG or PDF. iPhone HEIC photos are usually rejected and should be saved as JPG.
Are my documents uploaded?
No. The Image Workshop works entirely in the browser. IDs, certificates and application photos never leave your device.
