Compress JPG Online – Free JPEG Compressor

Make JPG photos smaller without changing their format. Set the size you need in KB or choose a quality level, for one photo or a whole folder.

How to compress a JPG

  1. Add your JPG or JPEG photos by tapping the box, dragging files in, or pasting a copied image with Ctrl+V.
  2. Choose how to compress. Target size fits each photo under a limit such as 200 KB. Quality lets you pick a percentage and see what you get.
  3. Optionally cap the dimensions with Resize – 1920 px suits most websites and slideshows, 1280 px suits email.
  4. Press Compress. Each photo takes about a second.
  5. Compare and download. Drag the slider over the preview to check the result, then download each photo or all of them as a ZIP.

Features

  • Stays JPG. Output is set to JPEG, so the files work in every app, printer kiosk and upload form.
  • Two ways to compress: an exact maximum in KB, or a quality percentage from 10% to 100%.
  • Metadata removed. GPS location and camera details are left out of the compressed file.
  • Resize option that shrinks oversized phone photos, the biggest single saving for most JPGs.
  • Batch and ZIP for an entire holiday album or product catalogue.
  • Before and after sizes for each photo, and the total saved across the batch.

Why compress JPG files with Fileora

JPG is the format phones and cameras already use, so most people don't want a different format – they want the same JPG, only lighter. This page keeps JPEG as the output from the start, so nothing surprises you when you open the file later.

Your photos are compressed on your own device by the browser's image engine. They are not uploaded, queued or stored anywhere, which is also why large batches finish quickly. There is no signup, no watermark and no limit on file count.

It runs on Windows, Mac, Android and iPhone in any modern browser, so you can shrink photos straight from your camera roll before sending them.

How JPG compression works

A JPG stores a photo as small blocks of colour and throws away fine detail the eye is least likely to notice. The quality setting controls how much is thrown away. That's why a busy photo of leaves or gravel stays large even at low quality, while a portrait against a plain wall shrinks dramatically.

Pixel count matters as much as quality. A 12-megapixel phone photo shown on a laptop is displayed at a fraction of its real size, so most of its data is never seen. Capping it at 1920 pixels removes that invisible data first; after that, even a high quality of 80% gives small files.

If your pictures are screenshots, logos or graphics with transparent backgrounds rather than photos, JPG isn't the right format – see Compress PNG instead. For photos going on a website, JPG to WebP saves even more. And to set exact pixel dimensions, such as 1080 × 1080 for a post, use the image resizer.

Frequently asked questions

How do I reduce the size of a JPG file?

Add your JPG, choose either Target size (a maximum in KB) or Quality (a percentage), and press Compress image. Save as is already set to JPG on this page, so the result stays a normal JPEG that opens everywhere.

What JPG quality setting should I use?

For photos you'll view on a screen, 70–80% is the sweet spot: files are often a third of the original size or smaller, and the difference is very hard to see. Go down to 50–60% for thumbnails and previews. Above 90% the file grows quickly for almost no visible gain.

Does compressing a JPG again make it worse each time?

Yes, a little. JPG is lossy, so every save throws away some detail. Always compress from the original photo rather than from a copy that has already been compressed, and keep the original if you might need it later.

Will the compressed JPG keep my photo's location and camera details?

No. The photo is redrawn and saved fresh, which leaves out the EXIF metadata – GPS location, camera model and capture settings. That makes the file slightly smaller and safer to share publicly. The photo keeps the right way up.

Can I compress JPEG photos in bulk?

Yes. Select or drop as many JPG files as you like. They are compressed one after another with the same settings, and a single button downloads them all as a ZIP.

Is JPG or WebP better for a smaller file?

WebP is usually 25–35% smaller than JPG at the same visual quality, and every modern browser supports it. JPG is still the safer choice for email attachments, printing services, older software and upload forms. If you only need the photo on a website, try JPG to WebP.
