- 1
Upload your image
Open the free image compressor and upload your JPG, PNG, or WebP file. The tool shows the original file size immediately after upload.
- 2
Set compression to 75-85%
Start at 75% compression. For most photos taken with a smartphone or camera, this reduces the file below 100KB. If the output is still above 100KB, increase to 85-90%.
- 3
Check the output file size
After compressing, the tool displays the output file size in KB and the percentage reduction. If you are above 100KB, increase the compression slider and compress again.

Why Do Websites Require Images Under 100KB?
Visa & passport photo portals
Most visa application systems (Schengen, UK, US, Canada) require passport-style photos under 100KB or 200KB. These portals run on government infrastructure with strict upload limits.
Job application & HR portals
Many HR systems and job boards require profile photos or CV attachments under 100KB. Compressing your photo before uploading ensures it is accepted without being rejected by the portal.
University & exam registration
University admission portals and exam registration systems (GMAT, IELTS, GRE) typically require photos between 50KB and 200KB. Compress your photo to meet their exact requirements.
Government & official documents
Tax portals, health system registrations, and official government forms often impose strict file size limits on uploaded documents and identification photos.
What Happens to Image Quality When You Compress to 100KB?
For a typical smartphone photo (3-8MB original), compressing to 100KB represents a 97-99% file size reduction. At this level of compression, you will see some quality reduction — but for a profile photo displayed at small sizes on a government portal or job application, the image will still be clear and recognisable.
For best results: crop your photo to the exact required dimensions before compressing. A smaller canvas needs fewer bytes to represent — so a 400×400px cropped portrait will compress to 100KB at higher quality than a full 4000×3000px photo compressed to the same size. Most visa and passport photo systems also specify exact pixel dimensions alongside the file size limit.
