PDFDrawerImage compressor — shrink JPG, PNG & WebP photos
To compress an image, drop it above and set the quality — for example, a 4.8 MB phone photo at quality 80 typically lands near 600 KB, visually near-identical on screen and small enough for any upload form, with the before and after sizes shown for every file before you download.
Output is JPG for photos (smallest for the quality). Already-small images may not shrink — you'll see both sizes either way.
🔒 Your files never leave your device. This tool runs entirely in your browser — nothing is uploaded to a server, so the document you open is the only copy that ever exists.
How it works
- Drop one or more images — phone photos, scans, screenshots.
- Set the quality and, if you like, a maximum width; most of the weight is in the pixels.
- Click Compress images, compare sizes, and download — singly or as a ZIP.
About this tool
Modern phone cameras are magnificent and enormous: a single photo can weigh 5 MB, which is five times what many upload forms, marketplaces and email systems will accept. Image compression trades a sliver of pixel perfection — most of it invisible on any screen — for a file a fraction of the size. At quality 80, the standard setting here, even picky eyes struggle to spot the difference side by side, while the file shrinks by 70–90%.
Two levers do the work, and the second is the stronger. Quality controls how aggressively each pixel is approximated; maximum width controls how many pixels there are. A 4000-pixel-wide photo destined for a screen that shows it at 1000 pixels is carrying four times the data it needs — capping the width at 1280 or 800 is where the dramatic savings live, and it is why the tool offers both levers rather than a single mysterious “compress” promise.
Every image is processed on a canvas inside your browser: your photos are never uploaded, which matters for the ID scans, documents and family pictures that most often need shrinking. The results list the exact before and after size of every file — if an image was already lean and barely changes, the numbers say so honestly instead of dressing up a copy as a compression.
Frequently asked questions
What quality setting should I use?
80 is the sweet spot for photos — big savings, no visible difference on screens. Use 90 for images that will be printed or closely inspected; 60–70 for thumbnails and previews.
Why did one of my images not get smaller?
Small or already-optimized images (many screenshots and web graphics) have little left to squeeze. The before/after list shows you exactly what happened to each file.
Does compressing change the dimensions?
Only if you set a maximum width — then larger images are scaled down proportionally. With “Keep original size,” dimensions are untouched.
What format do compressed images come out as?
JPG — the most efficient format for photographs at a given quality. If you specifically need PNG or WebP output, use the Image Converter.
Are my photos uploaded?
No. Compression happens on a canvas in your browser tab.
