Image size compression questions
To compress an image for a job application, choose 20 KB, 50 KB, or 100 KB (or enter the limit shown by the application), select your photo, and download the result. The image is resized only when quality adjustment alone cannot meet your requested size. FileVexa processes your photo locally, so it is not uploaded or shared.
How to compress image to 20KB for online job applications?
Choose the image from your device, select the 20 KB preset, and press Compress. FileVexa adjusts JPEG quality first and reduces image dimensions only if needed. Download the result and check that it meets the job application’s listed format and size requirements.
Are my photos uploaded to any server?
No. Your photo is decoded, compressed, previewed, and downloaded entirely in your browser. FileVexa does not upload the image to a server.
Can I compress an image to a custom KB size?
Yes. Enter any positive target size in the custom KB field, or choose one of the 20 KB, 50 KB, 100 KB, 200 KB, and 500 KB presets.
Which image formats can I compress?
You can select JPEG, PNG, WebP, or HEIC images. The compressed download is a JPEG file, which is widely accepted by online forms. Transparent areas in PNG and WebP images are filled with white because JPEG does not support transparency.

How to Compress an Image to a Specific Size in KB online in 3 Simple Steps
FileVexa compresses JPEG, PNG, WebP, and HEIC photos to a target size such as 20 KB, 50 KB, or 100 KB. Choose a preset or enter a custom size, then let the browser find the highest JPEG quality that fits. Resolution is reduced only when quality compression reaches its minimum. Image processing stays on your device; no photo is uploaded to a server.
- Choose an image: Select or drag in a JPEG, PNG, WebP, or HEIC photo. The image is decoded locally in your browser.
- Set the target size: Choose a 20 KB, 50 KB, 100 KB, 200 KB, or 500 KB preset, or enter any custom target size in kilobytes.
