How to Convert PNG to JPG or WEBP Online Free

Many online forms in India accept only JPG or JPEG. If you upload a PNG screenshot or a photo saved as PNG, the portal may reject it with "unsupported file type." Converting the format fixes this — and often cuts file size dramatically.

PNG vs JPG vs WEBP — Quick Comparison

• PNG — Best for logos, screenshots, and images with transparent backgrounds. Files are usually larger.
• JPG / JPEG — Best for photographs and form uploads. Smaller files, widely accepted everywhere.
• WEBP — Modern format with excellent compression. Great for web use; some old portals may not accept it yet.

Why Convert PNG to JPG?

• Government & job portals — Most require JPG only.
• Smaller file size — A 2 MB PNG photo can become 200 KB as JPG.
• Email attachments — JPG sends faster on slow mobile networks.
• WhatsApp sharing — Photos load quicker when not oversized PNGs.

Note: Converting PNG to JPG removes transparency. If you need a transparent background, keep PNG or use our crop tool first.

Step-by-Step: Convert Format with PhotoBandhu

1. Open the free Convert Image Format tool.
2. Upload your PNG, JPG, or WEBP file.
3. Choose the output format: JPG, PNG, or WEBP.
4. Adjust quality if converting to JPG (80% is a good starting point).
5. Download the converted file. Processing stays on your device — nothing is uploaded to our servers.

Common Problems & Fixes

• "Only JPG allowed" — Convert PNG → JPG, then check file size. If still too big, use Compress to KB.
• Blurry after conversion — Do not set quality below 70%. Resize first if the image is very large.
• Wrong colours on screenshots — PNG screenshots convert cleanly to JPG; avoid multiple re-saves.

After Converting: Hit KB Limits

Format change alone may not reach 50KB or 100KB targets. Combine convert + compress:

1. Convert PNG → JPG
2. Open Compress to KB and pick 50KB or 100KB
3. Upload to your form portal
