Free, browser-based, no upload required
Reduce any image below 100KB entirely in your browser. Job portals, university admission systems and corporate HR platforms reject photos above 100KB at the point of upload. This tool compresses your image to 96KB by default, giving a safe margin to pass the limit first time.

JPEG, PNG, WebP, AVIF, HEIC. All processing stays in your browser.
Default target is 96KB. Change the target in the field above if your portal specifies a different limit.
The 100KB limit is the most common file size restriction on job application platforms, university admission systems and professional examination portals. These platforms enforce the limit automatically, so you must reduce your image before attempting to upload.
Job application photo uploads
HR portals on Workday, SAP SuccessFactors and regional job boards frequently cap profile photos at 100KB. Your image must be below the limit before the form will accept it.
University and college admission portals
Admission and registration systems at universities across India, Nigeria, Pakistan and the UK commonly enforce a 100KB limit on applicant photographs.
Professional certification and exam registration
Competitive exam portals for civil services, engineering licensing boards and professional certifications typically require photos under 100KB for registration.
Corporate HR and intranet profiles
Internal HR systems and employee directory platforms often restrict profile photo uploads to 100KB to keep directory pages loading quickly.
These systems process large numbers of applications and store photos in databases alongside other applicant data. A 100KB ceiling keeps storage predictable and ensures uploaded photos load quickly inside employer or admissions officer review dashboards. The limit is enforced at upload time so the image must be below 100KB before submission.
When a portal says the file must be under 100KB, any file below 100KB passes. You do not need to hit exactly 100KB. This tool targets 96KB by default, providing a small margin that accounts for any byte-counting differences between browsers and upload servers.
Yes. At 96KB a typical professional headshot or passport-style photo is indistinguishable from the original at the sizes employer portals display it. The tool uses a binary search algorithm to find the highest available quality that fits within the target, so compression is minimal.
JPEG is the safest choice for any institutional portal, job board or government system. It is universally accepted. Use WebP only if you are certain the portal accepts it, as some older systems reject WebP files.
Yes. All compression happens in your browser using WebAssembly. Your photo never leaves your device and is never sent to any server. This is especially important when dealing with ID photos and personal portraits.
Yes. Upload the PNG and the tool decodes it in the browser before re-encoding it as JPEG or WebP. PNG files are often much larger than equivalent JPEGs, so a PNG profile photo that is several hundred KB will typically compress to well under 100KB with negligible visible difference.
