How it works
Upload the image or scan
Add the photo or document image you need to shrink.
Pick a portal preset or keep 100KB
Keep the 100KB target for GST, EPFO and e-District uploads, or pick an exam preset when the notification also fixes pixels.
Compress and check readability
The tool compresses the JPG under 100 KB. For document scans, check in the preview that the text is still readable — portals reject unreadable uploads.
Check and download
Confirm the size, then download the JPG and upload it on the portal.
Questions
How do I compress an image to 100 KB?
Upload the photo or scan, keep the 100 KB target and download the JPG. You see the final size before you download.
What is the GST photo size limit?
The GST registration checklist asks for a photo of every stakeholder (promoter, partner, director) and of the authorised signatory as JPG only, maximum 100 KB. Most proofs of the principal place of business — electricity bill, municipal khata copy, property tax receipt, consent letter — are JPG or PDF up to 100 KB each, while rent/lease agreements and constitution proofs get 1 MB.
What is the EPFO profile photo size?
The EPFO member portal takes a profile photo under 100 KB as JPG/JPEG (View > Profile > upload photo). EPFO KYC itself needs no document upload — you only enter document names and numbers, and Aadhaar-validated UANs update profile details without any file.
What if my document is not readable at 100 KB?
Portals reject unreadable scans — NSP's scholarship FAQ puts it as: 'The documents uploaded must be in readable mode otherwise application is liable to be rejected.' Scan flat in good light, crop to the document edges so no kilobytes go to the table around it, and check the preview text before downloading. A single A4 text page compresses to 100 KB and stays readable.
Is my image uploaded to a server?
No. Your image stays in the browser on this page. Nothing is uploaded.
