Como comprimir fotos para menos de 20KB ou 50KB
Learn how to compress JPG and PNG images down to exact target file sizes under 20KB, 50KB, or 100KB for government job and visa portals.
Government job portals, visa applications, academic admission systems, and bank KYC forms frequently reject photo uploads exceeding 20KB, 50KB, or 100KB. Using standard image editors often turns into frustrating trial-and-error where images end up either horribly pixelated or still slightly above the strict upload limit.
Most legacy photo compressors force you to guess with an arbitrary quality slider between 1% and 100%. If you set it to 60%, the file might be 62KB. If you set it to 50%, it drops to 18KB but looks unreadable.
With ILoveImages' browser-based compression engine, an adaptive binary search algorithm tunes quality and dimension scaling directly inside your browser memory to hit your exact kilobyte threshold with zero server uploads.

Perguntas Frequentes
Does reducing a photo to 20KB make it completely blurry?
Our engine optimizes quantization tables and strips non-essential EXIF metadata before scaling pixels, maintaining crisp legibility for IDs and passport portraits.
Can I compress multiple photos to 50KB at once?
Yes, you can drop up to 50 photos at once. Each photo will be individually calibrated to stay under your target threshold and exported in a single ZIP.
Is there any risk of my ID photo being saved on your servers?
None whatsoever. All compression runs locally inside your browser's WebAssembly sandbox. Not a single byte is transmitted across the internet.
