I built a tool that makes images bigger, not smaller – here's why
Almost every image tool on the internet does the same thing: make the file smaller . Compress, optimize, shrink. But there's a very common problem that goes the other way. The "file too small" problem In India, millions of people fill online forms every year – bank exams (SBI, IBPS), SSC, railway recruitment, college admissions.

Most image tools on the internet focus on reducing file size, compressing, optimizing, or shrinking images. However, a common issue arises when images are too small, particularly for online forms requiring specific file sizes. In India, millions of people submit online forms like bank exams, SSC, railway recruitment, and college admissions that mandate photo and signature uploads with strict file size rules (e.g., 20 KB - 50 KB). When a photo is cropped and the resulting file is smaller than required, it gets rejected.
Most users then look for ways to increase the image size, but end up on compression tools instead. This gap inspired the creation of IncreasePhotoSize, a tool that enlarges images rather than compressing them. The tool addresses three aspects of image size: file size (KB/MB), dimensions (pixels), and resolution (DPI). These aspects are distinct and changing one does not automatically affect the others. For example, a 72 DPI and a 300 DPI version of the same image can have identical pixels and appear identical on screen.
IncreasePhotoSize is designed to operate entirely in the browser, using the Canvas API, without uploading photos to any external server. This ensures user privacy and faster processing. The core functionality involves creating a bitmap of the uploaded file, creating a canvas with the desired dimensions, drawing the image onto the canvas, and then converting the canvas back to a blob.
The JPEG quality setting can be adjusted to increase file size while maintaining the same pixels. If quality adjustments aren't sufficient, the tool can also increase the dimensions.
To make the tool user-friendly, preset options for specific exams and a signature maker are provided. The site explains concepts clearly, such as the difference between file size, dimensions, and DPI, which many users find confusing. IncreasePhotoSize is free, requires no signup, and does not add watermarks. The creator invites feedback on the clarity of the explanations and any additional preset requirements users might find useful.
