Change Image DPI to 300 Online Free

Set your photo to 72, 150, 300 or 600 DPI for printing and online forms — free, no signup, no upload. Only the DPI label in the file changes: your pixels and image quality stay exactly the same, and nothing is recompressed.

🖼️ Click to choose photos
or drag & drop them here (JPG or PNG — as many as you like)

The tool first reads each photo's current DPI, so you can see what it was before the change. If a form or printer rejects your photo for DPI, this is usually the only fix it needs — but if it also needs more pixels for a large print, resize the photo first, then set the DPI here. WebP photos: convert them to JPG or PNG first with our Image Format Converter.

How to Compress a PDF to 1MB or 200KB for Free (No Signup)

Knowing how to compress a PDF to 1MB (or even 200KB) is essential when a job form, university portal, or email refuses your file for being too large. Scanned documents easily cross 10–20 MB. Here is how to shrink any PDF to the exact size you need — free, with no signup. Why You Need a Smaller PDF Job and exam forms often cap uploads at 1 MB or 200 KB. Email attachments get rejected or bounce above 20–25 MB. WhatsApp documents have limits too, and smaller files send faster on slow networks. What Makes a PDF So Large Scanned pages saved as images are the usual culprit — each page can be 1–2 MB. Embedded fonts, high-resolution images, and uncompressed scans all inflate the file. Compression works by downsampling images and removing redundant data, which is why a 15 MB scan can become 800 KB with barely visible difference.

How to resize a photo to 20KB for an online job form is one of the most searched how-to questions in South Asia — and for good reason.

Resizing beforehand saves you that panic.

How to Compress a Video for WhatsApp (Beat the 16MB Limit)

Learning how to compress a video for WhatsApp solves one of the app's most annoying limits: WhatsApp refuses to send videos larger than 16 MB. A one-minute phone recording is often 100–200 MB. Here is how to shrink any video under the limit — free, in minutes. Why WhatsApp Rejects Large Videos WhatsApp caps video messages at 16 MB so messages send fast even on slow networks. When you attach a bigger file, you get an error and the video never sends. The fix is compression: reducing the file size while keeping the video watchable. What the 16MB Limit Means in Practice Roughly 90 seconds to 3 minutes of video, depending on quality. A 5-minute 1080p recording will always need compressing. Sending as a document instead of a video raises the limit (up to 2 GB), but the recipient gets a file, not a playable video message.
