Compress Image to 20 KB — exact size, in your browser

Built for most form portals, low-bandwidth uploads, and identity documents like Aadhaar or passport photos. Free, no signup, no upload — your image never leaves your device.

How it works

How to compress a Image to 20 KB

  1. STEP 01
    Drop your image

    Pick the JPEG or PNG you need to fit under 20 KB.

  2. STEP 02
    Preview the result

    Click the thumbnail to A/B compare original vs compressed and tweak quality if needed.

  3. STEP 03
    Download

    BindMyPDF lands the file at or just under 20 KB and downloads it as a JPEG.

Why this works

Why this is the best way to compress Image to 20 KB

  • Lands exactly at 20 KB or less

    Binary-search algorithm iterates quality and dimensions to hit the target. Portals reject files even 1 byte over — we always stay under.

  • Crisp output, even at small targets

    Sharp profile shrinks dimensions intelligently instead of crushing JPEG quality, so scanned text stays readable.

  • In-browser, zero upload

    Your ID scan or passport photo never reaches our servers. Critical for KYC and sensitive uploads.

  • Bulk compression

    Drop a folder of images, set the same target for all, and download as a single ZIP.

FAQ

Frequently asked questions

How do I compress a JPEG to an exact KB target?+
BindMyPDF uses a binary-search algorithm that iterates JPEG quality and dimensions to land at or just under your target size. Pick a target preset (100KB, 200KB, 500KB, 1MB), drop your image, and click Compress.
Will it work for passport, PAN, KYC, SSC, UPSC or college portal uploads?+
Yes — those portals require specific KB caps (commonly 20–200KB), which BindMyPDF hits reliably. Use the "Sharp" quality profile to keep text legible after aggressive size reduction.
Does it support PNG or only JPEG?+
Both. Input can be JPEG or PNG. Output is always JPEG, which is what every form portal expects and what compresses to small sizes most efficiently.
Are my images uploaded to your server?+
No. Compression runs entirely in your browser via a Canvas / WebAssembly pipeline. Your images never leave your device.
Can I compress multiple images at once?+
Yes. Add multiple images, set defaults via the "Apply to all" panel, then click Compress. Two or more files are bundled into a single ZIP download.
Why is my compressed file slightly under the target (e.g. 195KB instead of 200KB)?+
The algorithm errs slightly under the target to guarantee uploads pass strict portals — many will reject files even 1 byte over. The result will always be ≤ the target you chose.
What's the difference between resizing and compressing to a KB target?+
Resizing changes pixel dimensions; compressing changes file size. BindMyPDF combines both — it lowers JPEG quality first, then if needed scales dimensions down, to reach your byte budget without making the image look blocky.
Does compression preserve image dimensions?+
It tries to. The "Sharp" profile may downscale to keep text crisp at small KB targets; "Original size" forces full dimensions and accepts more artifacts. Choose per image in the preview.
