Free Online Image Tools
Compress photos to practical file-size targets, resize them to exact pixel dimensions, convert image formats, or prepare common print photo sizes. Processing is designed to happen directly in your browser.
Compress Image
Reduce JPG, PNG and WebP file size.
Resize Image
Set pixels, scale and output format.
Photo Size & DPI
Convert physical dimensions to pixels.
Image Converter
Convert JPG, PNG and WebP locally.
Compress Image to Exact Size
Reduce an image toward a specific file-size target.
Resize Image to Exact Pixels
Create common image dimensions such as 100×100, 600×800, 1080×1080 or 1920×1080 pixels.
Convert Image Formats
Convert common image formats locally in your browser.
Advanced Image Utilities
Go beyond basic conversion: create favicons, inspect files, work with Base64, extract practical color palettes, verify hashes, clean metadata and build contact sheets.
Photo Size & DPI Tools
Common physical photo dimensions at 300 DPI, with calculated pixel output.
Useful for upload limits
Prepare photos for forms, applications, websites and other portals that enforce file-size rules.
No account required
Choose an image, process it in the browser and download the result without signing up.
Multiple image intents
Start from a KB limit, exact pixel dimensions, physical photo size, output format or a practical developer/design utility.
Choose an image tool by requirement
Start with the rule you were given instead of guessing at a compression slider. A KB limit calls for a target-size tool; a pixel requirement calls for an exact-dimensions tool; a print requirement needs physical size and DPI; and a format requirement needs a converter.
Common use cases
- • Government, exam and admission forms with KB limits.
- • Job applications and profile-photo uploads.
- • Website images that need smaller downloads.
- • Print photos where DPI and physical size matter.
- • Converting images for compatibility or web delivery.
Prepare a passport-style photo
Start with the current instructions from the passport, visa, exam or application portal. Crop the photo to the required aspect ratio, then match the specified physical size or pixels, followed by the file-size and format limits. Requirements vary by destination, so do not assume that one photo size works everywhere.
- 1. Check the official photo dimensions, format and KB limit.
- 2. Use the matching print-size or pixel-size tool.
- 3. Compress only after the dimensions are correct.
- 4. Verify the final file before uploading.
Prepare a signature image
Signature uploads are destination-specific. Check the portal's required pixels, physical dimensions, format and maximum file size before editing. Crop closely around the signature, resize to the required dimensions, then compress to the required KB limit without making the signature difficult to read.
- 1. Record the exact portal requirements.
- 2. Crop around the signature and preserve legibility.
- 3. Resize to the required pixels if specified.
- 4. Compress and verify the final format and file size.
Frequently asked questions
Can I compress an image to an exact KB limit?
Yes. Choose a target such as 50KB, 100KB, 200KB or 500KB. The target-size tools are designed for forms, applications and upload systems with file-size limits.
What is the difference between compressing and resizing an image?
Compression mainly reduces the data stored in the file, while resizing changes the pixel dimensions. When a strict KB limit is difficult to reach, reducing dimensions can help preserve better visual quality at the final size.
Which image format should I use?
JPG is a practical choice for photographs and broad compatibility. PNG is useful when lossless quality or transparency matters. WebP can provide smaller files for supported web workflows.
Can I prepare photos for an online application?
Yes. Start with the destination requirements, then use a target-size page for the KB limit and a pixel or print-size page when the form also specifies dimensions. The destination instructions always take priority.
Are the image tools useful on phones?
The pages are designed for modern mobile browsers. For sensitive documents or photos, check the individual tool privacy behavior before processing.
