About This Image Compressor
An image compressor reduces the file size of a JPG, PNG, WebP, or AVIF image by re-encoding it at a lower quality level or converting it to a more efficient format. This is essential for website speed, email attachments, social media uploads, and any workflow where large image files create friction. Unoptimised images are consistently one of the biggest causes of slow page load times and poor Google Core Web Vitals scores.
Need to do more with your images? You can convert compressed images to a PDF document with our Image to PDF tool, or resize images to exact pixel dimensions with our Image Resizer.
🔒 Your privacy is guaranteed. Unlike TinyPNG, Squoosh, and Compressor.io, this image compressor never uploads your files to a remote server. All compression happens locally in your browser using the HTML5 Canvas API — your images remain completely private and are never stored or seen by anyone else.
Who Should Use This Image Compressor?
What Quality Percentage Should You Use?
Quality controls how much image data is discarded during compression. The right setting depends entirely on the intended use of the image — not on personal preference. Here is a practical guide:
Print, portfolio, client deliverables. File size reduction is modest but quality is preserved for zooming and cropping.
Website images, blog posts, social media. Difference is invisible at screen size while file size drops 50–70%.
Email attachments and WhatsApp sharing. Small files that still look good on phone screens.
Thumbnails, placeholder images, internal previews. Visible quality loss acceptable in exchange for very small files.
JPG vs PNG vs WebP — Which Format to Choose?
The output format you choose has as much impact on file size as the quality slider. Here is when to use each one:
| Situation | Best Format | Why |
|---|---|---|
| Website images & blog posts | ✅ WebP | 25–35% smaller than JPG with same quality |
| Photos with no transparency | ✅ JPG | Smallest file for photographic content |
| Images with transparent background | ✅ WebP or PNG | JPG forces a white background — kills transparency |
| Screenshots and UI graphics | ✅ PNG or WebP | Lossless edges on text and icons |
| Email attachments | ✅ JPG | Universal compatibility across all email clients |
| Printing or archiving | ✅ PNG | Lossless — no quality degradation across re-saves |
How This Image Compressor Compares to TinyPNG, Squoosh & Others
Most popular image compression tools send your files to a server for processing. This tool is one of the few that compresses entirely in your browser — which means faster results and complete privacy with no upload delay.

Common Image Compression Problems & Fixes
📷 Compressed image looks blurry or pixelated
Increase the quality slider to 80–85% and switch to WebP format. WebP delivers better visual quality at the same file size compared to JPG. Avoid going below 60% for any image with text or fine detail.
📄 PNG file is larger after compression
PNG is lossless — compressing a PNG as PNG rarely saves much. Switch the Output Format to WebP. WebP supports transparency and typically cuts PNG sizes by 50–70% with no visible quality loss.
🚫 Compressed file is still too large
Lower the quality slider to 65–70%, switch to WebP format, and enable Max Width/Height to resize the image dimensions. Resizing from 4000px to 1920px alone can cut file size by 75% before any quality reduction.
🌏 EXIF location data still visible after download
Make sure the Strip EXIF Metadata checkbox is ticked before compressing. Compression alone does not remove EXIF data — you must enable this option explicitly each session as it is not saved between uses.
Frequently Asked Questions
-
It depends on the format and quality setting you choose. PNG compression is completely lossless — zero quality loss. For JPG and WebP, some detail is reduced at lower quality settings, but at 75–85% quality the difference is invisible to the human eye while file size drops by 60–80%.
-
WebP consistently gives the best compression — typically 25–35% smaller than JPG at equivalent quality, and much smaller than PNG. JPG is best when WebP is not supported. PNG is only recommended when you need a completely lossless image or transparent background without WebP.
-
No, never. All compression is performed locally inside your browser using the HTML5 Canvas API. Your image data never leaves your device and is not sent to any server, stored, or shared with anyone.
-
EXIF metadata is hidden information embedded inside image files — including GPS coordinates showing exactly where the photo was taken, your camera or phone model, date and time, and other personal details. Stripping it before sharing images online protects your privacy and also reduces file size slightly.
-
Yes. You can upload and compress up to 20 images simultaneously. All images are processed with the same settings in one click, and you can download everything as a single ZIP file when done.
-
For website images, the Web preset (WebP format, 80% quality) is ideal. It produces images that look identical to the original at normal viewing size while reducing file size by 60–80%. This significantly improves page load speed and Google Core Web Vitals scores.
-
PNG uses lossless compression, so the size reduction is minimal and some PNGs can even increase when re-encoded. The solution is to convert your PNG to WebP using the Output Format selector — WebP supports transparency and typically reduces PNG file sizes by 50–70%.
-
Use the Web preset or manually select WebP format at 80% quality. WebP at 80% is visually identical to the original at screen size while being 30–35% smaller than JPG at the same setting. For best results, also set a Max Width of 1920px to avoid serving oversized images to mobile users.
-
Yes. Open this page in Safari on iPhone or Chrome on Android, upload your photos from your camera roll, adjust the settings, and download the compressed images directly to your device. No app installation needed — everything runs inside your mobile browser.
-
Use the Email preset which applies JPG format at 65% quality. For most photos this produces files under 300KB that look perfectly sharp in email clients. If the image contains text or logos, use 75–80% quality instead to keep edges crisp.
