Get documents to about 250KB for NVSP voter ID, e-District and ESIC uploads. Processed entirely on your device.
Typically an identity proof, an address proof and a photograph. Each has its own size limit, and they are not always the same — read the instruction page rather than assuming one limit applies to all.
For a single page, almost certainly. Phone photographs of documents compress very well because most of their size is sensor noise rather than detail.
No. The whole process runs in your browser using your own device's processing power. The file never leaves your device, which matters for identity and financial documents.
Neither. The tool is free to use with no account and adds nothing to your document.
250KB is the sort of allowance used by NVSP voter-ID services, state e-District portals and ESIC. These forms usually want proof documents — address proof, age proof, identity proof — scanned and uploaded one at a time.
Address and identity proofs are usually photographed rather than scanned, often in poor light, which produces a large file with a lot of noise. Noise is expensive to store, so these files are frequently several megabytes for a single page. That is exactly the case this tool handles best.
Compression is one-way. Keep the original scan on your device in case the portal later asks for a clearer copy, or in case the upload has to be redone at a different size.
These portals usually provide a separate upload box for each proof, each with its own limit. Merging everything into one PDF is a common cause of rejection even when the total size is within bounds. Compress and upload each document into the field it belongs to.
Upload limits change between notifications and differ by document type, so treat 250KB as the size you were asked for rather than a universal rule. The instruction sheet on your application portal is the authority; if it names a different figure, use the matching page below.
Other sizes: 50KB · 100KB · 150KB · 200KB · 300KB · 500KB · 1MB · 2MB
