ποΈ Image Compressor
Shrink JPG, PNG, and WebP files with a quality slider. Live size readout.
Make Images Smaller Without Making Them Worse
Images are the heaviest part of almost every web page, email, and upload. A single unoptimized phone photo can be 5 MB; the same photo at web quality is 200 KB and looks identical on screen. This tool shrinks your images with a simple quality slider and shows the before/after file sizes live, so you always know exactly what you are trading. Pick JPG, WebP, or PNG output, optionally downscale, and download. Everything happens in your browser: no upload, no waiting, no watermarks.
Choosing Format and Quality
For photographs, JPG at quality 70 to 80 is the classic answer: it cuts 60 to 80 percent of the bytes with differences invisible at normal viewing. WebP does the same job 25 to 35 percent smaller, making it the best choice when the destination supports it (all modern browsers and most platforms do). PNG is lossless, so quality never drops, but photographic PNGs stay huge; reserve PNG for screenshots, logos, graphics with text, and anything needing transparency. The live readout lets you A/B formats on your actual image instead of guessing.
The quality slider is where the craft lives. From 100 down to about 80, file size plummets while visible quality barely moves: this is free savings. From 80 to 60, you trade subtle texture for bytes; fine for web, risky for print. Below 60, blockiness and smearing become obvious, acceptable only when a hard size limit forces it. If you need an exact size rather than a quality, the Compress Image to Target Size tool binary-searches it for you automatically.
Resize: The Biggest Lever
Nothing shrinks a file like fewer pixels. A 4000 px phone photo displayed at 800 px wide on a blog is carrying 25 times the pixels it needs. The resize control downsizes before compressing, compounding the savings. General targets: 1920 px wide for full-screen heroes, 1200 px for article images, 800 px for thumbnails and avatars. Shrinking first also makes the quality slider more forgiving, since artifacts hide better at smaller sizes.
Why Compression Matters
Speed is the obvious win: smaller images load faster, especially on mobile networks, and visitors leave slow pages. Google factors page speed into search rankings, so compression is genuinely free SEO. Storage and bandwidth bills shrink too, which matters at scale. And uploads with size limits, from job portals to marketplaces, stop rejecting your files. It is one of the highest-return habits in digital publishing: thirty seconds here saves every future viewer waiting.
Workflow Tips
Always compress a copy, never your only original; keep masters archived at full quality. Compress once at the final settings rather than repeatedly re-saving, since each lossy pass degrades further. For photos with people, check skin tones at 100 percent zoom before settling on a quality. And strip private EXIF GPS data with the EXIF Remover before publishing anything publicly.
Frequently Asked Questions
How do I reduce the file size of a photo?
Upload the image, pick an output format, and drag the quality slider down until the size looks right. The tool shows the original and compressed sizes live, plus the percentage saved. Click Download when happy. For photos, JPG at quality 70 to 80 typically cuts 60 to 80 percent of the bytes with no visible difference.
What quality setting should I use?
For photos headed to the web: JPG quality 70 to 80 is the sweet spot of size versus visible quality. For images with text, logos, or sharp graphics: PNG, or JPG at 90+. For archiving: keep the original untouched and compress only copies. When in doubt, compare at 100 percent zoom in the preview; if you cannot see a difference, neither will your visitors.
JPG, PNG, or WebP: which compresses best?
For photos, WebP usually wins: 25 to 35 percent smaller than JPG at the same visual quality. JPG is the universal fallback every device and site accepts. PNG is lossless, ideal for graphics, screenshots, and anything with text, but terrible for photos (huge files). This tool lets you try each format on your image and compare sizes directly.
Will compression hurt my image quality?
Lossy formats (JPG, WebP) discard some data, but at sensible qualities the loss is invisible. The damage comes from repeated re-compression: every save at low quality degrades further. Rule of thumb: compress once, from the original, at the final quality you need. PNG compression here is lossless, so quality never drops, though size savings on photos are modest.
Why is my PNG still huge after compressing?
PNG is lossless, so photographic detail simply does not compress much; a detailed photo can stay several MB as PNG no matter what. If size matters more than perfection, switch the output to JPG or WebP. PNG is the right choice for screenshots, logos, and graphics with flat colors, where it often beats JPG on both size and crispness.
Do compressed images load faster on my website?
Dramatically. Images are usually the heaviest part of a web page, and halving their bytes roughly halves their load time on slow connections. Google also uses page speed in rankings, so compression is free SEO. Aim for under 200 KB per image for web use, and serve responsive sizes so phones do not download desktop-sized files.
