An image compressor reduces file size so your photos pass upload limits without visible quality loss. Our free image compressor runs entirely in your browser, no server upload, no waiting in a queue. Drop in JPG, PNG, WebP or BMP files, set a target size in kilobytes, and download results tuned to the highest quality that still fits under your cap.

Whether you need to compress a passport photo to 50KB, shrink a resume headshot to 200KB, or batch-process twenty product images for an online store, this image compressor handles it in seconds. Unlike desktop tools that require installation, or cloud services that store your files on remote servers, everything here happens locally on your machine. That makes it one of the fastest and safest ways to compress images online.

How to Use This Image Compressor

1

Add your images

Drag photos into the box, click to choose, or paste with Ctrl+V. This image compressor accepts JPG, PNG, WebP and BMP — up to 20 files at once, 50MB each.

2

Set your target size

Pick a preset (20KB, 50KB, 100KB or 200KB) or type a custom limit. The compressor uses binary search to find the highest quality JPEG or WebP that stays under your cap.

3

Choose output format

JPEG is the default and works on virtually every portal. Switch to WebP for smaller files at the same visual quality, or use Quality mode for manual control over compression level and max width.

4

Download compressed files

Preview before-and-after sizes side by side, then download individual files or grab them all in a ZIP. Re-run the image compressor anytime with different settings — your originals stay on your device.

Why Use Our Image Compressor?

Exact Target Size, Not Guesswork

Most image compressors ask you to slide a quality bar and hope for the best. Ours binary-searches quality until the output lands at or below your KB limit — so a 100KB visa requirement means 100KB, not 130KB.

100% Browser-Local Processing

Files never leave your device. This image compressor uses the Canvas API and Web Workers in your browser, making it safe for passport scans, medical records and confidential documents.

Batch Compress Up to 20 Images

Compress an entire photo set in one go. Each file is processed independently with its own before/after stats, and you can download everything as a single ZIP archive.

Automatic EXIF Stripping

GPS coordinates, camera model and timestamp data are removed from every output. Government portals often reject photos with embedded location metadata — our compressor handles that for you.

JPG, PNG, WebP and BMP Support

Import any common format. Output as JPEG for maximum compatibility or WebP for smaller files. PNG output is available in Quality mode when you need lossless compression with a width cap.

Free with

No watermarks, no daily limits. Open the page, compress, and download — the image compressor is free for personal and commercial use.

Image Compressor Use Cases

Visa and Passport Applications

Embassy portals often cap photo uploads at 50KB or 100KB. Compress your headshot to the exact limit while keeping facial details sharp enough for automated verification.

Exam and University Registration

College entrance exams, certification tests and scholarship forms frequently impose strict file-size rules. Batch-compress ID photos and document scans to meet every requirement.

Job Application Portals

HR systems like Workday and Taleo reject oversized profile photos. Use the image compressor to fit within 200KB or custom limits without opening desktop software.

E-commerce Listing Photos

Marketplace platforms throttle upload speed for large images. Shrink product photos to a consistent target size before bulk-uploading to Shopify, Amazon or Etsy.

Email and Messaging Attachments

Many email providers block attachments over 1–5MB. Compress screenshots and photos to a few hundred kilobytes so they send reliably on mobile networks.

Website and Blog Optimization

Large hero images slow page load and hurt Core Web Vitals. Compress images to 100–200KB before uploading to WordPress, Notion or any CMS for faster rendering.

Image Compressor FAQ

What is an image compressor?
An image compressor reduces the file size of a photo by lowering compression quality and, when needed, resizing dimensions — while keeping the picture visually acceptable. Unlike simply renaming a file, a real image compressor re-encodes pixel data so the output is smaller in kilobytes. Our tool targets an exact size limit you choose, rather than asking you to guess a quality percentage.
How is this different from other online image compressors?
Most free image compressors upload your files to a remote server and return a smaller version. Ours processes everything locally in your browser, so sensitive photos never travel over the internet. It also uses binary search to hit a precise KB target — useful when a form says "must be under 100KB" rather than "reduce by 50%."
Which formats does the image compressor support?
You can import JPG, JPEG, PNG, WebP, BMP and GIF files up to 50MB each. In Target Size mode, output is JPEG or WebP (lossy formats required for aggressive compression). In Quality mode, you can also export PNG. EXIF metadata is stripped from all outputs.
Can I compress multiple images at once?
Yes. Add up to 20 images in a single batch. Each file is compressed independently with its own before/after size comparison. When finished, download files one by one or grab the entire set as a ZIP archive.
Will compressing reduce image quality?
Some quality loss is inevitable when shrinking file size, but our image compressor maximizes visual fidelity within your limit. It searches for the highest quality setting that still fits under your KB cap, and only reduces dimensions if quality alone cannot reach the target.
Is my data safe? Are files uploaded to a server?
No files are uploaded. The image compressor runs entirely in your browser using JavaScript and the Canvas API. Your photos stay on your device from start to finish. EXIF data — including GPS location — is removed automatically from compressed outputs.
What target size should I choose?
Check the upload requirement on the form or portal you are submitting to. Common limits are 20KB for tight government forms, 50KB for passport photos, 100KB for visa applications and 200KB for general job portals. If unsure, start with 100KB — you can always re-compress at a lower target.
