How to Use This Tool
Upload Your Image
Drag and drop your photo or signature from your computer or mobile device. You can upload multiple files at once for batch processing.
Select a Preset or Set Dimensions Manually
Choose a government exam preset (SSC, UPSC, IBPS, RRB, ADRE, APSC, Police), document preset (Passport, Aadhaar, PAN), or social media preset. Each preset auto-fills the correct dimensions and file size range. You can also enter custom width and height values.
Set Target File Size Range (Auto-Optimized)
Government exam presets automatically set both Min Size (KB) and Max Size (KB) fields. The tool intelligently compresses your image to land within this exact range (e.g., 30–49 KB for RRB Signature). If your image is naturally smaller than the minimum, the tool automatically adjusts the output to meet the required size — ensuring your file won't be rejected by exam portals.
Enable Signature Enhancement (For Signatures Only)
Turn on "Enhance Signature Mode" to automatically remove grey shadows and produce crisp dark ink on a clean white background. Only use this for signature images, not photos.
Enable White Background (For Photos Only)
Turn on "Set White Background" to replace colored or uneven backgrounds with pure white — ideal for passport and ID photos. Not recommended for signatures.
Click Resize Image
The tool processes your image locally in your browser. For government exam presets, it ensures the output falls within the required KB range and shows the result with a green (in range) or red (out of range) indicator.
Download
Instantly download your resized, compressed, and compliant image ready for online form submission. For multiple files, download as a ZIP archive.
⚠️ Note:
- Use/Enable "Enhance Signature Mode" only if you are uploading signatures only. For best results, upload a signature written/signed clearly on plain white paper.
- Use "Set White Background" for photos only (not signatures). For best results, upload photos taken against a plain, solid background.
⚠️ Important: Do not optimize/reduce/adjust sizes of your photo and signature together — upload each separately. First adjust your signatures, once done reset, and then adjust your photos.
💡 Tip: If your output shows a "Below minimum" warning, try uploading a higher-resolution source image. The tool works best when the source image has more detail to work with.
