How do I compress photo and signature for SSC CGL, UPSC, and IBPS online application forms?

Government exam portals strictly require photos between 20KB–50KB and signatures between 10KB–20KB. Select the 50KB preset for your passport photo and 20KB preset for your signature. iEditPDF maintains clear ink lines and facial sharpness so your application form is never rejected.

How do I compress an image to 20KB, 50KB, 100KB or 200KB online?

Choose the required 20KB, 50KB, 100KB or 200KB preset, or enter your own target size in KB. Upload your JPG, PNG or WebP image and iEditPDF automatically optimizes it to fit within your selected file-size limit.

How do I compress a photo or image to exactly 50KB or under 50KB online?

Select the '50KB' preset or enter '50' in the target size box. iEditPDF's client-side optimizer runs an automated iterative binary search solver that tunes JPEG quantization to compress the photo precisely under 50KB without making the face or text blurry. You can inspect the live file size before downloading.

How do I compress a signature image to 20KB and 140x60 pixels for online exam forms?

Online exam portals (such as UPSC, SSC, IBPS, and state government application forms) strictly require signature scans to be between 10KB and 20KB with dimensions like 140x60 pixels. Select the '20KB' preset on iEditPDF to compress your signature file directly in your browser with high contrast ink lines and zero watermark.

How do I resize a passport photo to 413x531 pixels (or 3.5 x 4.5 cm) under 50KB?

Standard passport photos require dimensions of 413x531 pixels (3.5 cm x 4.5 cm at 300 DPI) and a file size under 50KB. Use iEditPDF's Resize Image tool to set 413x531 pixels, then use the 50KB target compressor to generate a compliant passport photo ready for instant online submission.

How can I compress images to 100KB or 200KB for job applications and visa portals?

Select the '100KB' or '200KB' preset. iEditPDF analyzes your photo's pixel dimensions, strips unnecessary EXIF metadata, and outputs a lightweight JPG or WebP file optimized for email attachments, employment portals, and visa application websites.

How do I compress an image from 50KB to 100KB or reduce JPG file size without losing sharpness?

Enter your custom target (between 50KB and 100KB) in the target size field. iEditPDF preserves facial features and sharp edge contrast while discarding redundant color data, ensuring clean, legible photos every time.

Can I compress JPG, PNG and WebP images?

Yes. iEditPDF supports JPG, JPEG, PNG and WebP images for browser-based compression. Choose your target file size, process the image, review the result and download the optimized file.

Can I compress multiple images at once?

Yes. You can select multiple supported images and process them together. Each image is optimized according to your selected target size, and the results can be downloaded individually or as a ZIP file.

Are my photos and signatures uploaded to a server?

No. iEditPDF processes image compression directly in your browser. Your photos, signatures and documents are not uploaded to an iEditPDF server during compression, so your files remain on your device.

How does browser-based client-side image compression work under the hood?

iEditPDF utilizes HTML5 Canvas 2D and WebAssembly decoders directly within your browser. When you drop an image, the browser renders the uncompressed RGBA pixel buffer in local sandbox memory, strips privacy-invasive EXIF and GPS geolocation metadata tags, computes perceptual color distribution, applies chroma subsampling (4:2:0 for JPEG), and re-encodes the image stream with precision-tuned quantization tables. Not a single byte is transmitted over the internet.

How does iEditPDF guarantee exact target sizes like 20KB or 50KB for passport photos and signatures?

Government exam portals (such as UPSC, SSC, IBPS, and state PSC systems) reject documents that exceed strict thresholds like 20KB for signature scans or 50KB for passport photographs. Instead of forcing you to repeatedly guess quality percentages, iEditPDF runs an adaptive binary search solver that iteratively evaluates quantization steps and boundary dimensions until the output file fits directly below your specified ceiling with optimal facial contrast.

What is the difference between lossy JPEG compression and lossless PNG optimization?

Lossy JPEG compression uses Discrete Cosine Transform (DCT) to discard subtle color variations imperceptible to the human eye, enabling massive 70–90% size reductions ideal for photographs. Lossless PNG optimization relies on DEFLATE / LZ77 predictive filtering, preserving every pixel perfectly for digital artwork and transparent graphics. Converting photographic PNG files to modern WebP or optimized JPEG in iEditPDF shrinks file sizes dramatically without visible quality degradation.

Why is client-side image compression safer for government ID, passport, and signature uploads?

Uploading sensitive personal identification documents (such as passports, driving licenses, PAN cards, or scanned signatures) to cloud conversion websites exposes you to third-party data breaches, logging, and unauthorized training datasets. Because iEditPDF runs 100% locally in your device's browser memory, your confidential documents remain strictly in your custody at all times.

How do I compress an image to exactly 20KB, 50KB, or 100KB?

Upload your image, click the 'Target Max Size' tab, and enter your desired limit (e.g., 20KB for signatures, 50KB for SSC photos, or 100KB for admission portals). The smart binary search algorithm finds the highest visual quality that stays under that limit.

Why do government recruitment portals reject images over 50KB?

Government servers handle millions of applicants and strictly validate file sizes between 20.0 KB and 50.0 KB. Files over 50.0 KB or under 20.0 KB trigger automated form validation errors.

Will compressing a photo make text or facial details unreadable?

No. iEditPDF uses perceptual quantization which prunes invisible color noise while preserving edge contrast on facial contours, eyes, and handwritten signatures.

Can I compress multiple images simultaneously?

Yes, you can upload up to 30 images in a single batch, compress all of them to your target size, and download them in a single ZIP folder.

What is the best format for compressing photos: JPG, PNG, or WebP?

For government and exam portals, JPG/JPEG is the universally accepted format. For web optimization, WebP offers 30% smaller sizes with transparent background support.

Can I compare before and after compression side-by-side?

Yes, our interactive Split Slider lets you drag across the photo to inspect original vs. compressed detail before saving.

How do I compress a scanned signature without fading the black ink?

Use our contrast enhancement toggle during compression. It whitens the background paper while deepening black or blue pen strokes.

Can I compress photos on mobile phones (Android / iPhone)?

Yes, upload photos directly from your phone gallery or camera. Compression executes in seconds with zero data usage.

Are my personal pictures stored or viewed by anyone?

Never. All compression runs in client-side memory. No images are sent over the network or saved to any cloud storage.

Does iEditPDF add any watermark to compressed photos?

No, all downloaded photos are 100% clean and free of watermarks.

Photo ka size kam kaise kare KB me online?
