Custom Image Compressor — Set Your Own Size in KB
Type the kilobyte cap from your upload screen when it is not 20, 50, 100 or 200KB. Same browser engine as the preset pages — crop first, compress once from the original.
Custom size requirements
KYC and profile photo uploads
Website image optimization
Email and document attachments
Quick note
Match the number on the form. If it says 50KB or 100KB exactly, the preset pages are faster.
JPG is usually the best choice for photos. PNG should be used mainly when transparency is important.

Why use the custom tool
One compressor for multiple upload scenarios
The custom compressor is designed for workflows where the portal, form or client asks for a size that does not match a fixed preset.
Any KB target
Set your own target instead of staying locked to only 20KB, 50KB, 100KB or 200KB.
Useful for forms and websites
Handle document uploads, web optimization and profile photos from one place.
Phone-friendly workflow
Touch targets, readable spacing and fast actions make it simple on mobile devices.
Private processing
Images are compressed in the browser instead of being permanently stored on a server.
Practical compression tips
For photos, JPG usually gets the smallest file without making the workflow complicated.
Crop background space or large margins before compression if you need to hit a smaller size more reliably.
If the portal already tells you a fixed size, jump straight to the matching KB preset for even faster output.
How it works
Compress to any size in three simple steps
The custom studio keeps the same interface as the fixed presets, so users do not have to learn a second workflow just to change the KB target.
Upload your source image
Choose a JPG, PNG or WEBP file and check the preview before compression starts.
Set your own KB target
Pick the file size your portal or workflow needs instead of being locked to one preset.
Download the result
Save the compressed image and use it right away for forms, websites, emails or documents.
Preset shortcuts
Open a fixed compression target when you already know the requirement
Fixed-size pages are useful when a portal clearly tells you the file-size limit. They reduce clicks and help users reach the right result faster.

Image Compressor to 20KB
Best for strict government form and passport photo limits.
Compress Image to 50KB
Useful for profile photos and standard student portal uploads.
Compress Image to 100KB
Balanced detail for KYC, job portals and resume attachments.
Compress Image to 200KB
A better fit when clarity matters more than strict size reduction.
When presets do not match
Custom KB for odd portal limits — 80KB, 120KB, 350KB
Fixed pages cover 20, 50, 100, and 200KB because those numbers dominate Indian forms. This studio lets you type the cap printed on your screen — scholarship portals at 120KB, private college forms at 350KB, client briefs at exactly 240KB. I still recommend the preset page when your form matches one — fewer clicks, same engine.
If the form lists 80KB specifically, the dedicated 80KB page has extra notes for that traffic pattern.
How I set the slider
Match the form, not a round number
- Portal says max 150KB → target 145–150, not 100.
- Portal says below 30KB → use 20KB tool first; custom 30 is fine if the field is literal.
- No KB line, only "reduce size" → start 200KB, check preview, step down.
Format
JPG vs PNG vs WEBP here
Photos and signatures: JPG output. Screenshots with tiny text: try PNG input but JPG output for upload. WEBP only when the portal lists it — convert with WEBP to JPG before compressing for KYC.
Workflow
One pass from the original
- Upload gallery original — crop empty margins first.
- Enter the KB cap from the form (or slightly under if it says "below").
- Download, verify size in file properties, zoom content once.
- Need PDF? → JPG to PDF after image is correct.
