Compress image to 50 KB, 100 KB, or 200 KB
Editryk doesn't pin you to a single byte target — instead, this guide tells you which Manual-mode quality settings reliably hit each common size for a typical 2–4 MB smartphone photo.
| Target size | Recommended setting | Best for |
|---|---|---|
| 10–20 KB | Manual 10–20% + Preserve Pixels off | Tiny avatars, signature uploads |
| 20–50 KB | Manual 20–30% + Preserve Pixels off | Most exam portals, ID document uploads |
| 50–100 KB | Manual 30–45% (Preserve Pixels on) | Profile photos, forum avatars, 100 KB form caps |
| 100–300 KB | Manual 50–70% | Email attachments, WhatsApp, blog images |
| 300 KB – 1 MB | Smart mode or Manual 75–85% | Hero images, product shots, social media posts |
| 1 MB+ | Manual 90–100% (near-lossless) | Print, portfolios, archival masters |
Tip: turn off Preserve Pixels when you need to drop below 50 KB — quality and resolution scale together.
How to compress an image
Three clicks from a bloated photo to a web-ready file. Nothing to install, nothing to sign up for.
- 1
Drop your images
Drag and drop one image or hundreds. JPG, PNG, WebP, AVIF, GIF, BMP, and TIFF are all supported, with files up to 50 MB each.
- 2
Pick Smart or Manual
Smart mode auto-tunes for the best size-to-quality ratio (TinyJPG style). Manual mode gives you a 10–100% quality slider plus a Preserve Pixels toggle to control dimensions.
- 3
Compress and download
Hit Compress All. See exact byte savings per file in real time. Grab a single file or download every result as a single ZIP — originals are untouched.
Compress photos for job applications, government forms & exam portals
Most application portals reject photos that exceed strict KB and pixel caps. Use the references below as a starting point — then fine-tune the quality slider until the live byte counter sits inside the allowed range.
Passport, visa & job application photos
| Document / portal | Specification | Notes |
|---|---|---|
| US passport photo (online submission) | 600 × 600 px · under 240 KB JPG | Department of State eForm cap |
| UK passport photo (digital) | 750 × 930 px min · 50 KB – 10 MB JPG | Gov.uk online application |
| Schengen / EU visa photo | 35 × 45 mm · typically under 500 KB | Most consulate portals |
| Canadian passport photo | 420 × 540 px · under 240 KB | IRCC PR online portal |
| LinkedIn / professional headshot | 400 × 400 px · under 8 MB | Auto-resized on upload |

India: SSC, UPSC, RRB, IBPS, NEET & GATE specifications
| Exam body | Photo | Signature |
|---|---|---|
| SSC (CGL, CHSL, MTS, GD) | 3.5 × 4.5 cm · 20–50 KB | 4 × 2 cm · 10–20 KB |
| UPSC (CSE, CDS, NDA) | 3.5 × 4.5 cm · 20–300 KB | Varies · 20–300 KB |
| RRB (Railways) | 3.5 × 4.5 cm · 20–50 KB | 3.5 × 1.5 cm · 10–30 KB |
| IBPS / SBI Bank PO/Clerk | 200 × 230 px · 20–50 KB | 140 × 60 px · 10–20 KB |
| NEET / JEE | 3.5 × 4.5 cm · 10–200 KB | 3.5 × 1.5 cm · 4–30 KB |
| GATE / CAT | 200 × 260 px · 5–200 KB | 150 × 60 px · 5–30 KB |
Why portals reject photos
- File size above the listed KB cap → compress harder in Manual mode
- Pixel dimensions outside the spec → use the Resize tool first
- Wrong format (HEIC, BMP, WebP) → convert to JPG with the Format Converter
- Background not white / off-white → use the Background Remover and add a white fill
Recommended workflow
- Resize to the exact pixel spec the portal lists
- Convert to JPG if it isn't already
- Drop into Editryk, switch to Manual mode
- Slide quality down until the byte counter is inside range
- Download — done in under a minute
Always cross-check the official notification — portals occasionally tighten limits between application cycles.

Lossy vs lossless compression — which should you use?
Both reduce file size, but they trade quality and savings very differently. The right choice depends on your image content, not the file extension.
Lossy compression
Throws away visual data the human eye barely notices. Used by JPG, WebP (lossy), and AVIF.
- Savings: 60–95%
- Quality: Tunable — visible artifacts below 30%
- Best for: Photos, hero images, thumbnails
- Editryk modes: Smart mode and Manual mode
Lossless compression
Re-packages every pixel byte-for-byte without throwing anything away. Used by PNG and WebP (lossless).
- Savings: 10–35%
- Quality: Pixel-perfect, byte-identical output possible
- Best for: Screenshots, logos, line art, transparency
- Editryk modes: Manual mode at 95–100% on PNG/WebP
Image compression for web performance & SEO
Image weight is the single largest contributor to slow load times on the modern web. Compressing the right way isn't optional — it's a Core Web Vitals requirement.
Largest Contentful Paint (LCP) — Google's most visible Core Web Vital — is almost always the hero image on a landing page. Cutting that hero from 800 KB to 120 KB typically moves LCP from poor (over 4 s) to good (under 2.5 s) on a mid-range Android device. That single change usually moves a PageSpeed score by 10–20 points.
Cumulative Layout Shift (CLS) doesn't depend on file size, but compressing without resizing means the browser still has to download a 4000-pixel-wide image just to render it at 800 pixels. Pair this compressor with the Resize tool for proper image sizing.
Recommended sizes per role:
- Hero images: 100–200 KB WebP
- Above-the-fold content images: 50–100 KB
- Thumbnails & cards: 15–40 KB
- Background images: 150–300 KB at most
Editryk's output also strips EXIF metadata by default, which trims another 5–30 KB of camera and GPS data per file — small wins that compound across hundreds of images.

Who uses an online image compressor?
Web developers and designers drop hero images and screenshots through Editryk before deploying — every kilobyte cut translates directly into faster LCP and lower CDN bills.
E-commerce store owners compress product photography in batches so listings on Shopify, WooCommerce, and Etsy load quickly on mobile, lifting conversion rates without reshooting.
Bloggers and content creators shrink featured images and editorial graphics to keep posts under page-weight budgets without sacrificing visual quality.
Email marketers compress hero images so newsletters stay under Gmail's 102 KB clipping threshold and render in full on every device.
Photographers and creative pros generate web-ready exports from RAW or TIFF originals without round-tripping through Photoshop, and without worrying that proofs end up cached on a third-party server.
Job applicants and exam candidates compress passport-style photos and signatures to the strict KB caps that government and HR portals enforce — without paying a cybercafe and without uploading IDs to an unknown server.
Frequently asked questions
Everything worth knowing before you compress your first image.
How do I compress an image to exactly 50 KB or 100 KB?
Use Manual mode and start at 30–40% quality. If the result is still over 50 KB, switch off Preserve Pixels so the dimensions scale down with the quality. For 100 KB targets, 50–60% quality usually lands within range on a typical 2–4 MB photo. The live size readout updates after each compress so you can dial it in.
Will my image quality look bad at low compression settings?
Below ~25% quality you start to see blocky artifacts on smooth gradients (skies, skin tones). Photos hold up far better than flat graphics — for diagrams, screenshots, and logos, prefer PNG or WebP lossless mode rather than aggressive JPG compression.
Are my images uploaded to a server?
No. Every byte stays on your device. Editryk runs compression locally in your browser using Web Workers — there is no upload step, no temporary cloud storage, and nothing to delete afterward. Safe for ID cards, medical images, and confidential designs.
What is the best image format for the web?
WebP is the sweet spot in 2026 — supported in every major browser and roughly 25–35% smaller than JPG at equivalent visual quality. AVIF compresses tighter still (up to 50% smaller) but encodes more slowly. JPG remains the safest fallback for email and very old systems. PNG is best reserved for screenshots, icons, and anything that needs transparency.
Why is my PNG still huge after compression?
PNG is lossless, so the compressor can only optimize the encoder — not throw away pixel data. If your PNG is a photograph, convert it to WebP or JPG first (use the Convert Image tool) and then compress. You'll typically see a 70–90% reduction.
Can I batch-compress hundreds of images at once?
Yes. Drop in a whole folder. Editryk processes files in parallel using Web Workers and bundles every result into a single ZIP for download. There's no upload limit and no per-batch cap — only your device's RAM matters in practice.
Does this work on iPhone HEIC photos?
If your browser can preview the HEIC, yes. Safari handles HEIC natively. Chrome and Firefox don't, in which case you'll want to convert HEIC to JPG first using the Convert Image tool, then compress.
How does compression affect SEO and Core Web Vitals?
Image weight is the single biggest factor in Largest Contentful Paint (LCP), which Google ranks. Cutting hero images from 800 KB to 120 KB usually moves LCP from "poor" to "good" on mobile and lifts overall PageSpeed scores. Editryk's output is also strip-cleaned of EXIF metadata, which trims a few extra KB.
What's the difference between Smart and Manual mode?
Smart mode behaves like TinyJPG — it picks an aggressive default that targets roughly 65% size reduction with no visible quality loss for typical photos. Manual mode hands you a 10–100% quality slider and a Preserve Pixels toggle so you can chase a specific KB target or a specific look.
Is there a maximum file size I can compress?
The dropzone accepts files up to 50 MB each. Beyond that, compression still works but very large RAW or TIFF files may slow your browser. There's no cap on the number of files in a batch.
