Is this image compressor really free and safe to use?

Yes, it's completely free with no sign-up. It runs entirely in your browser using the Canvas API, so images are never uploaded to a server.

How much can I compress an image without losing quality?

Most photos can be compressed to 60-80% quality with no visible difference, often reducing file size by 50-80% depending on the image content.

Can I compress multiple images at once?

Yes. You can upload many images at once, apply the same settings to all of them, and download the results individually or as a single ZIP file.

What does target file size do?

It automatically finds the highest image quality that still keeps the file under a size limit you specify, in kilobytes.

Does compressing remove metadata like GPS location?

Yes, re-encoding through canvas strips EXIF metadata including GPS location, camera model and timestamps, while correctly applying the orientation before discarding it.

Quick Answer

This image compressor reduces file size by re-encoding your photos with smart quality settings and optional resizing — directly in your browser. Nothing is uploaded to a server, so it works instantly and keeps your files completely private.

What Is This Image Compressor?

This is a free, browser-based tool for shrinking image file sizes without sacrificing visual quality. Whether you're optimizing product photos for an online store, attaching screenshots to an email, prepping images for a website, or saving storage space on your phone's camera roll, this tool handles it in seconds.

Unlike most online compressors, every step — decoding, resizing, re-encoding, and the final download — happens locally on your device using your browser's built-in Canvas engine. Your images never leave your computer or phone.

How to Use This Tool

Add your images

Drag and drop one or many images into the upload box, or tap it to choose files from your device. JPG, PNG, WebP, GIF, and BMP are all supported.

Choose an output format

Keep the original format, or convert everything to JPEG, PNG, or WebP — useful when you need a consistent format across many files.

Pick a compression level

Use a quick preset (Best Quality to Smallest) or drag the Custom quality slider. Or flip on "Target an exact file size" to let the tool find the right quality automatically.

Resize if needed (optional)

Fit images within a maximum dimension, scale by percentage, or enter exact pixel dimensions with locked aspect ratio.

Compress and download

Tap "Compress All Images", then download each file individually or grab everything at once as a ZIP.

Advanced Features

Batch Processing

Upload and compress dozens of images at once — perfect for entire product galleries or photo albums.

Format Conversion

Convert between JPEG, PNG, and WebP on the fly — great for switching legacy PNGs to lightweight WebP.

Quality Presets & Custom Slider

Choose Best Quality, Recommended, Small, or Smallest — or fine-tune compression with a 1–100% slider.

Flexible Resizing

Fit within a max dimension, scale by percentage, or set exact width/height with aspect-ratio lock.

Target File Size

Tell it "under 100 KB" and the tool automatically finds the highest quality that fits your limit.

Auto Rotation Fix

Detects EXIF orientation from phone cameras and rotates images upright automatically before compressing.

100% Private

No uploads, no servers, no tracking of file content. Everything runs in your browser's memory.

One-Click ZIP Download

Download each compressed image individually, or grab the entire batch as a single ZIP file.

JPEG vs. PNG vs. WebP: Which Format Should You Use?

Choosing the right output format matters as much as the quality setting. Here's how the three most common web formats compare:

Format	Best For	Compression	Transparency
JPEG	Photos, complex images with gradients	Lossy — small files	No
PNG	Logos, screenshots, graphics with text	Lossless — larger files	Yes
WebP	Modern websites, general-purpose use	Lossy or lossless — smallest files	Yes

Rule of thumb: use WebP for websites whenever possible (25–35% smaller than JPEG at the same quality), JPEG for maximum compatibility with photos, and PNG only when you need transparency or crisp text/line-art.

Recommended Settings by Use Case

Use Case	Format	Max Dimension	Quality
Website / blog images	WebP	1920px	75–80%
E-commerce product photos	JPEG / WebP	1500px	80–85%
Social media posts	JPEG	1080px	80%
Email attachments	JPEG	1024px	60–70%
Profile pictures / avatars	JPEG / PNG	500px	80%
Logos & icons (with transparency)	PNG / WebP	Original	n/a (lossless)

Tips for Better Compression Results

Resize before compressing. A 4000px photo shrunk to 1200px almost always produces a far smaller file than the same photo at full size with a lower quality setting — and looks sharper too.
80% quality is the sweet spot for most photos. Below 60%, you'll start to notice blurring and color banding, especially in skies and gradients.
Use the Target File Size option when a platform enforces a strict upload limit (e.g., "images must be under 200 KB").
Switch PNG screenshots to JPEG or WebP if they don't need transparency — PNG screenshots are often 3–5x larger than necessary.
Batch by category. Compress photos and graphics separately, since they need different quality settings for the best results.

Frequently Asked Questions

Yes — it's completely free with no sign-up required. It's also private by design: your images are processed entirely in your browser using JavaScript's Canvas API. No file is ever uploaded to a server, so there's nothing to intercept or store.

Most photos can be compressed to 60–80% quality with no visible difference to the human eye, often shrinking file size by 50–80%. The exact result depends on the image's content — busy, detailed photos compress better than smooth gradients or text-heavy graphics.

Yes. Drag and drop or select as many images as you like, set your compression and resize options once, then click "Compress All Images." Each file is processed individually, and you can download them one-by-one or all together as a ZIP.

When enabled, you enter a maximum size in kilobytes (e.g., 100 KB), and the tool automatically tries different quality levels until it finds the highest quality that still fits within your limit — useful for platforms with strict upload size restrictions like job portals or government forms.

Phone cameras often save photos with an EXIF "orientation" tag instead of physically rotating the pixel data. This tool reads that tag and rotates the image correctly before compressing, so your output always displays right-side-up across all devices and platforms.

Yes. Re-encoding an image through the browser's canvas strips EXIF metadata — including GPS location, camera model, and timestamps — by default (aside from the orientation tag, which is read once to fix rotation, then discarded). This is a useful privacy bonus when sharing photos publicly.

For screenshots with mostly text and sharp edges, PNG preserves crispness but can be large. If file size matters more than pixel-perfect text, convert to JPEG at 75–85% quality or WebP — both shrink screenshots significantly with minimal visible difference.

Downscaling (making an image smaller) does not reduce per-pixel quality — it actually tends to make images look sharper since detail is concentrated into fewer pixels. Avoid upscaling (making an image larger than its original size), as that adds blur without adding real detail.
