Reduce JPEG files to a practical upload size while keeping them usable for photographs, product images, and social media.
Drag in one file or a full batch. The uploader handles typical JPG workflows such as email attachments, website assets, and portal submissions.
Pick 150KB when you need to meet a form limit, shrink page weight, or stay under an attachment cap. The engine balances compression ratio and visual quality automatically.
Download the compressed output individually or as a ZIP archive, then use it immediately for uploads, publishing, sharing, or storage cleanup.
150KB is the sweet spot for most JPG files — good visual quality with significantly reduced file size. Photos look sharp at web resolution and documents remain fully readable.
At 150KB, most users will not notice quality differences compared to the original. Suitable for screen viewing, standard printing, and professional sharing.
JPEG is commonly used for photographs, product images, and social media. Typical originals land around 2–5 MB, so compressing to 150KB is most useful when you need to meet a strict upload or performance target.
These are the most practical reasons people compress JPEG files to 150KB.
Visa applications, tax portals, and identity verification forms frequently require documents under 150KB. Compress to meet strict upload limits.
150KB balances visual quality and fast loading. Ideal for Instagram, Facebook, LinkedIn, and X posts without triggering aggressive platform recompression.
Keep newsletter images at 150KB to ensure fast rendering across email clients. Total email size stays under 2 MB for reliable inbox delivery.
Built for target-size compression, repeatable results, and practical delivery workflows.
Upload and compress multiple JPG files to exactly 150KB simultaneously. Download all results individually or as a single ZIP archive.
Your files are processed securely and deleted automatically after compression. Nothing is stored, indexed, or shared with anyone. Ever.
Our algorithm iteratively adjusts compression to land as close to 150KB as technically possible — not an approximation, but a precise target.
Compress files directly in the browser. No plugins, desktop apps, or extra setup are required.
Files are processed securely and deleted automatically after compression, which keeps upload workflows private and easier to trust.
CTET (Central Teacher Eligibility Test) and various state TET forms accept photos up to 150 KB, as does the DigiLocker "Add photo to profile" flow. Uploading a stock 3 MB smartphone JPG here gets you a silent rejection; the form saves everything else but leaves the photo field blank until you re-upload something within the cap.
JPG uses lossy DCT compression tuned by a single quality parameter (0-100). A stock 3 MB smartphone JPG typically starts at quality 92. Reaching a small size target means dropping quality, and the relationship is non-linear: the first 40% size cut is nearly invisible (quality 92 → 80); the last 40% is where visible artefacts appear — mostly ringing near sharp edges (text, faces at close crop), colour banding in blue skies, and blockiness in flat backgrounds. Our compressor iterates quality downward until the size cap is met, so photos with lots of flat area hit the target at higher quality than detail-heavy ones.
Every compressor makes a trade-off between file size and visible quality. Here's what happens under the hood, and how to get the smallest file that still looks the way you need it to.
The drop zone accepts single images or batches. Free-tier uploads are limited to 10 MB per file — enough for most phone photos and standard web images. Pro handles files up to 1 GB and batches of up to 20 at once. Every filename is preserved.
The algorithm iterates the quality setting until the result lands close to 150KB, then stops. That means the output isn't a fixed quality preset — it's calibrated to the size target, so the same tool produces bigger visible quality on a small source and heavier compression on a large one.
The compressed file downloads immediately once ready — typically a couple of seconds per image. Preview the output at full size before shipping it: aggressive size targets on large sources can introduce visible blocking or blur that\'s worth catching before submission. Both the upload and the compressed output are deleted from our servers within 30 minutes.
Most compressors ask you for a "quality" slider and expect you to guess. Portals and forms don\'t care about your quality slider — they care whether the file is under 150KB. Targeting a specific size directly is a much more honest workflow: you tell the tool the byte count you need, it does whatever compression is required to hit that number, and you preview the result to make sure the quality is still workable.
Six specific scenarios where hitting an exact size ceiling is the actual job.
Visa applications, passport renewals, driving-licence uploads, and tax portals routinely cap photo uploads at very specific byte counts — 150KB is a common ceiling. Hitting it exactly means one upload attempt instead of five, and no rejection email 48 hours later.
Gmail caps attachments at 25 MB, corporate systems often lower. A stack of high-res photos blows past the limit fast. Compressing each to 150KB keeps the email deliverable without splitting into three follow-ups.
Core Web Vitals treat page-weight seriously — every hero image over about 100 KB drags your Largest Contentful Paint score. Compressing to 150KB before upload keeps individual images inside the sensible-web-image range.
WhatsApp, Signal, and Telegram re-encode images on upload — the recipient sees whatever quality the app decided on. Compressing to 150KB upfront means you control the trade-off rather than leaving it to the app\'s default (which is usually more aggressive than you would pick).
A 500-photo trip in RAW or full-res JPG eats gigabytes. Batch-compressing to 150KB preserves the memories while making the archive cloud-storable, backup-friendly, and searchable without dragging your library app to a crawl.
Photo-print services, calendar makers, and merchandise platforms often specify a max file size per image, then reject anything above. 150KB is a common target that hits their cap while leaving enough quality for standard print sizes.

Short version: you can't. JPG doesn't support transparency, so converting means flattening it. Here's what actually happens and when it matters.
