Image Compressor - Shrink JPG, PNG and WebP to Any Exact Size Free

Introduction: Image Compressor Online Free

The Image Compressor by Trencada shrinks your image files without ruining how they look, right in your browser. Drop in a PNG, JPG, or WebP image, pick a quality level, and download the lighter version — free, with no sign-up and no watermarks. Large images slow down websites, eat up storage, and make sharing a pain. This tool re-encodes your image at the quality you choose and shows you exactly how much smaller it got, so you can balance size against clarity with confidence. Everything happens on your own device: your image is never uploaded to a server, never stored anywhere, and never shared. Close the tab and nothing remains.

How to Compress Images

1. Upload your image — Drag and drop a PNG, JPG, or WebP file into the upload area, or click to browse and select it. Files up to 20MB are accepted.
2. Choose quality and format — Move the quality slider (10–100%, default 85%) to trade size against clarity, and pick an output format: JPEG, PNG, or WebP.
3. Compress — Click “Compress” and the tool instantly shows the original size, the new size, and the exact percentage saved.
4. Download or copy — Save the compressed file to your device, or copy it straight to your clipboard. Use Reset to start over with another image.

Quality and Format Settings

JPEG is the best choice for photos when you want the smallest files. PNG suits graphics with sharp edges and transparency. WebP gives the best compression of the three wherever it is supported. A quality setting around 80–85% keeps most images looking identical while cutting size dramatically — if you notice banding or soft text, nudge the quality up and compress again.

Will compressing a PNG reduce its quality?

Not if you keep the PNG format. PNG uses lossless compression, so the image stays pixel-identical no matter how much smaller the file gets — unless you also shrink its dimensions. Visible quality loss only happens if you convert the PNG to JPEG, which is a lossy format. Rule of thumb: keep PNG for logos, graphics, and anything with transparency; switch to JPEG at 80-85% for photos, where the difference is invisible but the savings are much bigger. Need a transparent background? Remove the image background before compressing.

Why Compress Images with Trencada?

Smaller images mean faster websites, quicker uploads, and less storage — and you do not need to hand your files to a stranger’s server to get them. This compressor runs entirely in your browser, so private photos and client work stay private. It is free for unlimited use with no account and no watermark. Working with documents too? You can compress a PDF the same way, or convert images to PDF when you need a document instead.

Frequently Asked Questions (FAQ)

Is the Image Compressor free?

Yes. It is completely free with no sign-up, no watermarks, and no usage limits.

Are my images uploaded to a server?

No. Compression runs entirely in your browser using on-device code, so your images never leave your computer.

Which formats are supported?

You can upload PNG, JPG/JPEG, and WebP images up to 20MB, and save the result as JPEG, PNG, or WebP.

Will compression reduce image quality?

Slightly, at lower quality settings — that is the trade-off for smaller files. Around 80–85% the difference is usually invisible, and the tool shows the exact size saving so you can decide.

Can I compress multiple images at once?

The tool handles one image at a time, so each file gets your full attention on quality settings. Just hit Reset and drop in the next image.

What is the maximum file size?

20MB per image. If your file is larger, reduce its size in a photo editor first, then upload it here.

Do I need to install anything?

No. The compressor works entirely in your browser — nothing to download or install.

How do I compress an image to an exact file size?

Switch from "By quality" to "By target size", enter your target in KB (or tap a preset like 100 KB, 200 KB, 500 KB, or 1 MB), and the compressor automatically tries qualities from high to low until your image fits the target. If the exact target cannot be reached, it keeps the closest result and tells you.

Does compressing remove EXIF or location data from my photos?

Yes. Because the compression runs entirely in your browser via canvas, metadata such as EXIF and GPS location is not carried over into the compressed file — a useful privacy side-effect.

Should I choose JPG, PNG or WebP when compressing?

JPG gives the smallest files for photos. PNG is lossless — best for screenshots, logos and text, but larger. WebP offers the best of both and works in all modern browsers. The compressor lets you convert between all three.

Reduce Photo Size for the Web

This tool also works as a photo size reducer and JPG file compressor: drop in a JPG or PNG photo, pick how much to shrink it, and download the smaller file. It is ideal when a photo is too large to email, upload to a form, or publish on a website.</p

Can I compress an image to fit a form upload limit?

Yes. Set the exact size limit from the form, for example 50KB or 100KB, and compress to that target before uploading.

Which output format gives the smallest file?

WebP usually gives the smallest file for photos, JPEG is the most widely compatible choice, and PNG is best when you need lossless quality. You can save as JPEG, PNG, or WebP.
