Image Compressor
Fixpio’s image compressor shrinks JPG, PNG and WebP files in your browser — with a quality slider, resizing, batch processing and a target-size mode that can compress an image to 200 KB or any limit you set.
Compress your images
Add images, set quality or a target size, then compress.
Compression with nothing to hide
Real techniques, real numbers, no uploads.
Lossy vs lossless, honestly
JPG and WebP shrink files by discarding detail your eyes barely miss — that is where the big savings are. PNG compression here re-encodes and resizes; it cannot magic a photograph small without changing dimensions.
Quality 75–85 is the sweet spot
For most photos, quality around 80 keeps images looking sharp while cutting 60–80% of the weight. Below 60, artefacts start to show on detailed images.
Resize before you upload
A 4000-pixel phone photo displayed at 800 pixels wastes megabytes. Setting a maximum width is often the single biggest saving available.
About this image compressor
This image compressor reduces the file size of JPG, PNG and WebP images directly in your browser. Add one image or a batch, then either set a quality level yourself or switch on target-size mode and enter a limit — compress an image to 200 KB, 100 KB, 50 KB or any figure a stubborn upload form demands — and the compressor searches for the highest quality that lands at or under it. Every result shows the original size, the compressed size, the dimensions and the exact percentage saved, so you can judge the trade-off yourself before downloading.
The savings come from the same techniques the big compressor sites use: re-encoding JPG and WebP at a lower quality setting (the format discards fine detail the eye is unlikely to notice), and resizing images that are larger than their display size. PNG is the honest exception — it is a lossless format with no quality dial, so for PNG the tool re-encodes and, in target mode, steps the dimensions down until the file fits, and tells you it did so. If a target genuinely cannot be reached, the tool returns the smallest version it could make and labels it as such rather than claiming success.
Because everything runs locally, there is no upload queue, no file-size cap imposed by a server and no copy of your images stored anywhere. That makes the tool safe for personal photos, client deliverables and screenshots containing private information. Batch processing handles a list of images one after another, each with its own download — your original files are never modified.
Frequently asked questions
Sizes, targets, quality and privacy — answered honestly.
How much can an image be compressed?
It depends on the image. A large JPG photo typically shrinks 60–85% at quality 80 with no visible difference on screen. Screenshots and graphics with flat colour compress less predictably, and an already-optimised image may barely shrink at all — the tool shows the real percentage either way, and warns you if a result came out larger.
How do I compress an image to exactly 200 KB (or another size)?
Tick “Compress to a target size”, enter 200 (KB), and convert. For JPG and WebP the tool automatically tries quality levels until the result fits under the target at the best quality. For PNG it reduces dimensions step by step, since PNG has no quality setting. If the target is unreachable, you get the smallest possible file and a clear note saying the target was not met.
Will compression ruin my image quality?
At sensible settings, no visible difference for typical on-screen use. Quality 75–85 keeps photos looking sharp; very low settings (under 50) and repeated re-compression do degrade images. Keep your originals — the tool never overwrites them — and avoid compressing an already-compressed file a second time.
Are my images uploaded to a server?
No. Decoding, compression and downloads all happen in your browser using its built-in image engine. Nothing is sent to Fixpio, there is no storage, and the tool still works if you disconnect after the page loads.
Which format should I choose?
Keep the original format unless you have a reason to change. Choose JPG for photographs going almost anywhere, WebP for the smallest web files on modern browsers and sites, and PNG when you need lossless graphics or transparency — accepting that PNG files stay comparatively large.
Is there a limit on file size or number of images?
There is no server limit because there is no server. Practical limits are your device’s memory: very large batches of huge photos may be slow on a phone. On a typical laptop, batches of dozens of images are fine.
