About the Image Compressor
Image Compressor shrinks JPG, PNG, and WebP files to a fraction of their original size while keeping them looking great. Drop one image or a hundred — quality, format, and dimensions are all under your control, and the tool flags exactly how many bytes you saved on each file.
Everything happens inside your browser. Your photos are never uploaded, never queued on a server, and never logged. Close the tab and they're gone — that's why screenshots, ID scans, product shots, and anything else sensitive are safe to run through it.
What you can control
- Output format: Auto keeps each file's original type, or force everything to JPG, PNG, or WebP.
- Quality slider (1–100): Drives JPG and WebP compression. The 75–85 range is usually the sweet spot — visually identical, dramatically smaller.
- Max dimensions: Set a width and/or height ceiling in pixels and the tool resizes while preserving aspect ratio. Smaller files get even smaller; larger files get downsized automatically.
- Strip metadata (EXIF): Removes camera info, GPS location, timestamps, and edit history — great for privacy and for shaving extra kilobytes.
- Only save if smaller: Skips files where compression would actually make them bigger, so already-optimized images pass through untouched.
- Batch processing: Compress dozens of images in one pass and download them individually or as a single ZIP.
- Before/After compare slider: Drag to see exactly what each compression setting did to a chosen image.
Common uses
- Speeding up website and blog pages by serving lighter images.
- Trimming email and Slack attachments to fit size limits.
- Preparing photos for marketplace listings (eBay, Etsy, Facebook Marketplace).
- Compressing batches of social media uploads without burning quality.
- Archiving photo libraries to save disk space or cloud storage.
- Slimming images for slide decks, PDFs, and documentation.
Tips for the best results
- Start at quality 80 — most images look indistinguishable from the original at that setting.
- Use WebP when you can. It typically delivers 25–35% smaller files than JPG at the same visual quality.
- Keep PNG for graphics, logos, and anything with transparency. Force-converting them to JPG kills the transparent background.
- For web use, capping the longest edge at 1920 px is plenty — most screens never render larger anyway.
- Leave "Only save if smaller" on by default. It prevents the tool from accidentally enlarging files that were already well-optimized.
- Stripping EXIF is a quick privacy win — especially before sharing photos taken on a phone.
No accounts, no watermarks, no upload queue — just drop, tune, and download. If you compress the same kinds of images often, save your settings mentally: format, quality, and max dimensions are usually the only knobs you need to revisit.
Common questions
How do I compress an image without losing quality?
Use the quality slider and the before/after comparison: most photos shrink 60 to 80 percent before any visible difference appears. You judge with your own eyes at full size, then download exactly what you approved.
How do I make an image smaller for a website or form upload?
Drop it in, pick a quality level (and optionally a smaller resolution), and download. Combining mild compression with sensible dimensions gets most phone photos from several megabytes to a few hundred kilobytes.
Can I compress many photos at once?
Yes. Batch a whole folder, apply the same settings across the set, and download everything in one ZIP, with per-image savings shown.
JPG, PNG, or WebP, which should I use?
JPG for photos, PNG for graphics with sharp edges or transparency, WebP when the destination supports it (smaller than both). The compressor converts between them so you can pick per use.
Are my photos uploaded during compression?
No. Compression runs entirely in your browser, so private photos stay private and huge batches start processing immediately instead of uploading first.
